Jessie uses 20 liters of gasoline to travel 200 kilometers, how many liters of gasoline will he use on a trip of 700 kilometers?

Sagot :

Proportion Problem:

Let x be the liters of gasoline required for a 700-km trip.

20 is to 200; x is to 700.

20/200 = x/700

(200) (x) = (20) (700)

200x = 14,000

200x/200 = 14,000/200

x = 70 

The answer is 70 liters.
