Question

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

Answer 1

Answer:

187.5 feet

Step-by-step 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

$\frac{25}{2}\frac{ft}{rev}=\frac{x}{15}\frac{ft}{rev}\\\\x=15(25)/2\\\\x=187.5\ ft$

Answer 2

Answer:

Max's bike after 15 rotations will move:

• 187.5 feet

Step-by-step 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
