A van travels 260 miles on 13 gallons of gas. Find how many gallons the van needs to travel 500 miles?
FinnZ [79.3K]

Answer:

  25 gallons

Step-by-step explanation:

Assuming miles-per-gallon is a constant, the amount of gas is proportional to the miles driven:

  gallons/(500 mi) = (13 gal)/(260 mi)

  gallons = (500 mi)/(260 mi)(13 gal) . . . . multiply by 500 mi

  gallons = 25 gal . . . . do the arithmetic

The van will need 25 gallons of gas to go 500 miles.
