Charlotte's car used \frac{1}{90} of a gallon to travel \frac{1}{2} of a mile. How many miles can the car go on one gallon of gas?
Answer:
The car go 45 miles on one gallon of gas
Explanation:
From the above question
1/90 gallons of gas = 1/2 mile
1 gallon of gas = x mile
Cross Multiply
1/90 × x = 1/2 × 1
x = 1/2 / 1/90
x = 1/2 × 90/1
x = 45 miles
Hence:
The car can go 45 miles on 1 gallon of gas.
