Six friends work for a company as maintenance staff.
Above are six graphs. Each graph shows the distance that one of the six is from his home from 8 AM to 9 AM on a particular day, relative to the time. The time of day is represented by the horizontal axis, and the distance from home is represented by the vertical axis. The name of the person represented by each graph is under the graph.
Of the six, which one works the night shift, and therefore went from work to home between 8 AM and 9 AM?
Since the person in question went home, his distance from home decreased rather than increased as time went on. The graph will be a falling line; this graph represents Mr. Palin.

What is the least common multiple of 6 and 8?
One easy way to find the least common multiple is to take the largest of the numbers given to you, and find its multiples.
8: 8, 16, 24, 32, 40, 48...
Now start with 8, and see if any of these numbers is divisible by 6. The first number that is divisible by 6 is the least common multiple of 6 and 8.
8: No
16: No
24: Yes
24 is the least common multiple of 6 and 8.

Sophie travels f miles in g hours. She must drive another 30 miles at the same rate. Find the total number of hours, in terms of f and g, that the trip will take.
Using d = rt, we know that first part of the trip can be represented by f = rg. The second part of the trip can be represented by 30 = rx, where x is some unknown number of hours. Note that the rate r is in both equations because Sophie is traveling at the same rate as mentioned in the problem.
Solve each equation for the time (g in equation 1, x in equation 2).
g = f/r
x = 30/r
The total time is the sum of these two times
Note that, from equation 1, r = f/g, so
=

Gary is the getaway driver in a bank robbery. When Gary leaves the bank at 3 PM, he is going 60 mph, but the police officers are 10 miles behind traveling at 80 mph. When will the officers catch up to Gary?
Traveling 20 mph faster than Gary, it will take the officers 30 minutes to catch up to Gary. The answer is 3:30 PM.

Trevor took a road trip in his new VW Beetle. His car averages 32 miles per gallon. Gas costs $4.19 per gallon on average for the whole trip. How much would it coust to drive 3,152 miles?
To find this answer just do total miles divided by miles per gallon in order to find how many gallons of gas it will take to get from point A to Point B. Then multiply that answer by the cost of gasoline per gallon to find total amount spent on gasoline.

Jason is driving across the country. For the first 3 hours, he travels 60 mph. For the next 2 hours he travels 72 mph. Assuming that he has not stopped, what is his average traveling speed in miles per hour?
In the first three hours, he travels 180 miles.
In the next two hours, he travels 144 miles.
for a total of 324 miles.
Divide by the total number of hours to obtain the average traveling speed.

Joe drove an average of 45 miles per hour along a 60-mile stretch of highway, then an average of 60 miles per hour along a 30-mile stretch of highway. What was his average speed, to the nearest mile per hour?
At 45 mph, Joe drove 60 miles in hours.
At 60 mph, he drove 30 miles in hours.
He made the 90-mile trip in hours, so divide 90 by
to get the average speed in mph:

Tom runs a 100m race in a certain amount of time. If John runs the same race, he takes 2 seconds longer. If John ran at 8m/s, approximately how fast did Tom run?
Tom runs a 100m race in a certain amount of time. If John runs the same race, he takes 2 seconds longer. If John ran at 8m/s, how fast did Tom run?
Let denote the amount of time that it took Tom to run the race. Then it took John
seconds to run the same race going 8m/s. At 8m/s, it takes 12.5 seconds to finish a 100m race. This means it took Tom 10.5 seconds to finish. Running 100m in 10.5 seconds is the same as

Kate and Bella were both travelling at the same speed. Kate went 300 miles in 5 hours. Bella travelled 450 miles. How many hours did it take for Bella to reach her destination?
The distance formula is essential in this problem.
First, use Kate's info to figure out the rate for both girls since they're travelling at the same speed, which is . Then, plug in that rate to the formula with Bella's information, which gives her a time of
hours.

Suppose a student ran a pace of eight minutes per mile at consistent pace. He arrived at the school in thirty minutes. How far is the school in miles?
The consistent pacing tells us that this is a linear relationship between distance and the student's speed and time.
Write the equation for the distance travelled.
The speed can be rewritten as:
Substitute the speed and time.

On a map, one half of an inch represents thirty miles of real distance.
The towns of Waterbury and Nashua are three and one half inches apart on this map. How long, in hours, would it take for someone to drive from Waterbury to Nashua if his speed averaged miles per hour?
On a map, one half of an inch represents thirty miles of real distance, so one inch represents twice this, or sixty miles. The actual distance from Waterbury to Nashua, which is three and a half inches on the map, is
Therefore, the two cities are 210 miles apart. Divide the distance by the rate to get the time:

On a map, one half of an inch represents forty miles of real distance.
It takes John 90 minutes to get from Kingsbury to Willoughby driving an average of miles per hour. How many inches apart, in terms of
