An athlete rides his bike 8 miles for every 3 miles that he runs. if the athlete runs 4.5 miles, how far does he ride his bike?

Given,

Athlete rides bike for 8 miles if he runs 3 miles

To find,

How far will athlete ride if he runs 4.5 miles?

Solution: - From above situation we take miles for which athlete will ride bike = X

Then the ratio will be

8:3 = x: 4.5

8/3 = x/4.5

Solving this will give 12.

Hence, athlete will ride bike for 12 miles if the athlete runs 4.5 miles.
