Question

A van travel 300 miles on 15 gallons of gas how many gallons the van needs to travel 360 miles

Answer 1

300 : 15 = 360 : x
x = 15 * 360 : 300
x = 18 (gallons for 360 miles)

Answer 2

First we need to decided 15 by 300, to see how much gas it took for each mile.
I got 0.05, so now we know it takes .05 gallons of gas for each mile.
Now we multiply 0.05 by 360 to get our answer, 18.
You would need 18 gallons of gas to travel 360 miles.
