Question

Walking at the rate of 4 kmph a man covers certain distance in 2 hours 45 min. Running at a speed of 16.5 kmph the man will cover the same distance in how many minutes?

Answer 1

Answer:

speed of man=4kmph

time taken=2hours 45 mins=2.75 hours

speed=distance/time  => distance=speed*time

distance=4*2.75=11km

thus,

if he travels with a speed of 16.5 kmph he can cover the distance in 11/16.5=0.67 hours

which means 40 minutes.
