Question

A woman jogs the same distance in 50s and then stands at the end point for 50s. what is her average speed over 100s interval?

Answer 1

Answer:

400 M in 50 secs, add 10 secs for a minute, so plus 20% so equals 480 M per minute.

If it were 500 M per minute it would be 30 Kilometres per hour.

480 is 96% of 500 (48 x 2)

One percent of 30 is .3 so 4% is 1.2 so he is running at 28.80 Kms hour
