Question

A horse 64 feet from the center of a merry-go-round makes 27 revolutions. In order to travel the same distance, how many revolutions would a horse 16 feet from the center have to make?

GUYS, PLEASE HELP URGENTLY!! THNX!
BTW THE ANSWERS:6.75 and 1 1/5 are wrong! =)

Answer 1

108

Explanation:

The radius of the circular path of the horse closer to the center is 1/4 of the radius of the path of the horse farther from the center. Since circumference is directly proportional to radius, the length of shorter path is 1/4 of the length of the longer path. Therefore, 4 times as many revolutions must be made to go the same distance, which is 27x4= 108

Answer 2

108

Explanation:

64*27=1728

1728/16=108

or

64/16=4

4*27=108

hope this helps!
