Answer:
L = 882/121 feet
Step-by-step explanation:
Set the appropriate variables in the equation to the given values and solve for the unknown.

_____
<em>Additional comment</em>
That's about 7.3 feet. (You can compare this to what you know about the time it takes for a cycle when swinging on a swing set.)
Answer:
The car uses less gas
They use the same amount of gas after
miles
Step-by-step explanation:
Given
The table represents the car mileage
--- The van
First, calculate the car's slope (m)

From the table, we have:

So, we have:



Calculate the equation using:



implies that for every mile traveled, the car uses 1/40 gallon of gas
Also:
--- The van
By comparison to: 

This implies that for every mile traveled, the van uses 1/5 gallon of gas.
By comparison:

This means that the car uses less gas
Solving (b): Distance traveled for them to use the same amount of gas.
We have:
--- The van
--- The car
