Question

man walks 190 m in 48 seconds and another 250 m and 62 seconds find the average speed in kilometre per hour



ANSWER WITH STATEMENTS .

Answer 1

Given:
distance 1 = 190 m
distance 2 = 250 m
time 1 = 48 seconds
time 2 = 62 seconds

Formula:
average speed = total distance / total time
= 190 + 250 / 48 + 62
= 440 / 110
= 4 m/s
Conversion from m/s to km/h
= 4 * 5/18
= 1.11 km/h
