Question

The distance Max's bike moves is directly proportional to how many rotations his bike's crank shaft has

made. If Max's bike moves 25 feet after two rotations, how many feet will the bike move after 15 rotations?

Answer 1

Max's bike after 15 rotations will move:

• 187.5 feet

Explanation:

Since the exercise provides the information that after 2 rotations the bike moves 25 feet, you must divide that distance by the number of rotations to obtain the distance traveled per rotation:

• Rotation distance traveled = 25 ft / 2 = 12.5 ft

Having the distance for each rotation made, you only have to multiply this value by the total number of rotations (15):

• Total distance traveled = 12.5 feet * 15 = 187.5 feet

Answer 2

187.5 feet

Explanation:

we know that

Max's bike moves 25 feet after two rotations

so

using proportion

Find out how many feet will the bike move after 15 rotations

Let

x ----> the distance in feet

`(25)/(2)(ft)/(rev)=(x)/(15)(ft)/(rev)\\\\x=15(25)/2\\\\x=187.5\ ft`
