Answer:
Step-by-step explanation:
From the given table,
A. The unit rate for each car is,
Car A =
= 32 miles per gallon
Car B =
= 34 miles per gallon
Car C =
= 35 miles per gallon
Car D =
= 31 miles per gallon
B. From the derived values in A, the car that uses the least amount of gas is Car C.
C. Total distance covered = 496 miles x 4
= 1984 miles
The gallons of gas the Car A would need for the journey can be determined by;
Car A requires 1 gallon for 32 miles
So that for 1984 miles =
= 62 gallons
Car A would need 62 gallons of gas to make the trip.
D. Amount spent on gas for Car A = $2.12 x 62
= $131.44
E. speed =
⇒ time =
Given the for Car A, speed = 68 miles per hour.
time =
= 29.1765
time = 29 hours
It would take approximately 29 hours for Car A to cover the total distance of 1984 miles.
