A particular hybrid car travels approximately 123 mi on 3 gal of gas. Find the amount of gas required for a 779​-mi trip.

Answer 1

To find the amount of gas required for a 779​-mi trip, we first need to determine the miles per gallon (MPG) of the hybrid car.

Given that the car travels approximately 123 mi on 3 gal of gas, we can calculate the MPG as follows:

MPG = 123 mi / 3 gal = 41 mi/gal

Now, we can use the calculated MPG to determine the amount of gas required for a 779​-mi trip:

Gas required = 779​ mi / 41 mi/gal ≈ 19 gal

Therefore, the amount of gas required for a 779​-mi trip is approximately 19 gallons.
