a boat cab travel 12 miles on 4 gallons of gasoline. how far can it travel on 15 gallons?

12/4= x/15 X= 45

13.6

To determine how far the boat can travel on 15 gallons of gasoline, we need to find the ratio of the distance traveled to the amount of gasoline used.

Given that the boat can travel 12 miles on 4 gallons of gasoline, we can set up a proportion to solve for the distance it can travel on 15 gallons of gasoline.

Distance_1 / Gasoline_1 = Distance_2 / Gasoline_2

Let's substitute the given values into the proportion:

12 miles / 4 gallons = Distance_2 / 15 gallons

To find the unknown distance, we can cross-multiply and solve for Distance_2:

4 gallons * Distance_2 = 12 miles * 15 gallons

4 * Distance_2 = 180

Dividing both sides of the equation by 4:

Distance_2 = 180 / 4

Therefore, the boat can travel 45 miles on 15 gallons of gasoline.
