A. 43 miles
B. 270 miles
C. 405 miles
D. 420 miles

1 answer

To solve this problem, we need to use the ratio of miles per gallon.

The car travels 28 miles on 1 gallon of gas, so:

1 gallon of gas = 28 miles

To find out how many miles the car can travel on 15 gallons of gas, we can set up a proportion:

1 gallon of gas = 28 miles
15 gallons of gas = x miles

Solving for x, we can cross-multiply:

1 gallon of gas * x miles = 15 gallons of gas * 28 miles
x = 420 miles

Therefore, the car can travel 420 miles on 15 gallons of gas.

The answer is D. 420 miles.
