Question 708135
What is the proportion to this word problem?

A motorcycle can travel 705 miles on 19 gallons of gasoline. How many gallons of gas are needed to travel 1253 miles?


19/705 = x/1253

Cross multiply:

19 * 1253 = 23807

705 * x = 705x

Therefore:

705x = 23807

Divide each side by 705.

705x/705 = 23807/705

x = 37.1 gallons

He needs 37.1 gallons to travel 1253 miles.
