Sara drives 96 miles on 3.2 gallons of gas. she uses this information to calculate how many miles per gallon she can drive. using this result, how many miles can sara drive on 12.5 gallons of gas?

Hi

96 miles ⇒ 3.2 gallons
x miles ⇒ 12.5 gallons

3.2x = 96·(12.5)
3.2x = 1,200
x = 1,200/3.2
x = 12,000/32
x = 375 miles

or

96/3.2 = 960/32 = 30 miles/gallon

1 gallon ⇒ 30 miles
12.5 gallons ⇒ x miles

x = 30·(12.5)
x = 375 miles

375 miles

He secknd step was the answer to them
