Question

ashokcompletes acomplete round of a circular park of radius 70m in 3 min what is his speed.

Answer 1

distance=70 m or 0.07 km
time =3 min or 0.05 hr
speed =distance/time
     = 0.07/0.05
            =1.4 km/hr

Answer 2

We know that, Speed = Distance / Time and the standard unit of speed is m/s so 3 min = 180 secs.
Applying the same values in the formula,
Speed = 70 / 180
           =  0.389 m/s
