Question

a car uses 32 L of gas to travel 450 KM. how many liters would be required to drive 800 km (to the nearest tenth)?

Answer 1

Answer: 56.88 L

Explanation:

Let L represents number of liters

A Car uses 32 L of gas to travel 450 km.

Write a proportion for the problem using rates.

450/32 = 800/L

Cross product is 450*L = 800*32

450L = 25600

Divide each side by 450.

450L/450 = 25600/450

L = 56.88
