Answer :
From the calculations, the speed of the jogger is calculated as 4.7 m/s.
What is speed?
The term speed refers to the ratio of distance covered to time taken. In this case we know that;
steps per minute = 200 steps per minute.
1 stride length = 140 cm
Distance covered in 200 strides = 200 * 140 = 28000 cm or 280 m
time taken = 1 minute or 60 seconds
Speed of the jogger = 280 m/60 seconds = 4.7 m/s
