Question

Jeffrey drives 434 miles on 14 gallons of gas. How many miles will he drive on 2 gallons of gas?

Answer 1

Here, we need to set up a proportion. 

Jeffery: 434 miles on 14 gallons of gas

We need to know how many miles he can drive on 2 gallons of gas.

Proportion:-

434/14 = x/2

Cross multiply!

434*2 = 868
14*x = 14x

14x = 868

14x/14 = 868/14
x= 868/14
x= 62

Jeffery can drive 62 miles on 2 gallons of gas. 

Answer 2

With 1 gallon of gas, Jeffrey can drive:
434 miles/ 14gallons of gas* 1 gallon of gas= 31 miles
Since there is 2 gallons of gas, Jeffrey can drive:
31 miles/ 1gallon of gas* 2 gallons of gas= 62 miles
Hope this will help :))
