Answer 1

Answer:

Step-by-step explanation:

From the given table,

A. The unit rate for each car is,

Car A = $\frac{416}{13}$

          = 32 miles per gallon

Car B = $\frac{544}{16}$

          = 34 miles per gallon

Car C = $\frac{665}{19}$

          = 35 miles per gallon

Car D = $\frac{775}{25}$

          = 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 = $\frac{1984}{32}$

                                    = 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 = $\frac{distance}{time}$

⇒ time = $\frac{distance}{speed}$

Given the for Car A, speed = 68 miles per hour.

time = $\frac{1984}{68}$

       = 29.1765

time = 29 hours

It would take approximately 29 hours for Car A to cover the total distance of 1984 miles.
