Question

Truck drivers report the mileage or the number of miles (M) traveled per gallon of gas (G) for each trip. Which driver went the farthest on one gallon of gas.

Answer 1

Answer:

• B. Andy

Step-by-step explanation:

Kelly's mileage

This is proportional relationship, so one pair of coordinates is enough for our calculation, point (20, 50):

• m = 50/20 = 2.5 g

Andy's mileage

Use one pair of points from the table to calculate (15, 78.75):

• m = 78.75/15 = 5.25 g

Rick's mileage is given:

• m = 4.8 g

Comparing, we see Andy's mileage is largest.

Andy will travel farther than the other drivers.
