Answer 1

From the word problem, we can conclude that if 355miles = 17gallons, 284miles = x amount of gallons 

 

We can use this information to create a ratio:

355/17 = 284/x

 

We can then use cross multiplication to get the answer. 
355x=(284)(17)

355x=4,828

x=355x/355=4828/355
x=13.6 gallons (which will be your answer!)
