Question

A jogger jogs around a circular track with a diameter of 225 m in 15 minutes. What was the jogger's average speed in m/s?
___ m/s

Answer 1

Answer #1

there are 60 sec in 1 min
so 15*60 = 900
there are 900 sec in 15 min.
so, 225/900 meters per second

simplify that to 1/4 meters per second

ans = 0.25 m/s

Answer 2

Answer #2

circumference is pi*d=225*pi.

Speed is d/t=225*pi/(15*60)

v=0.785398163 m/s

Answer 3

Answer #3

225m(pi)=706.86 m (this is the circumference of the track)

60 sec(15) = 900 sec (you're trying to find m/s)

706.86/900 = .7854 m/s
