Question

Keeping his speed the same, John takes 1.5 times as much time to jog once along the outer edge of the circular track shown here as compared to the inner edge.What is the width of the track if the radius of the inner edge is 24 m?  36 m 24 m 15 m 12 m​

Answer 1

Answer:

12 meters

Step-by-step explanation:

The inner circle has a circumference of 2π*24 m =48π m.. The outer side of the track must be 1.5 times the circumference - 1.5 x 48π m = 72π meters. The radius of the outer side must be 72π m/2π = 36 m. The width of the track is the difference: 36 m -24 m= 12 meters.

The track is 12 meters wide.
