Question

A Suppose you walk across a room of length 9m with a velocity of one and a half kilometre per hour.
Express this velocity in m/s and find the time you will take to move across the room ?

Answer 1

1.5 km/hr = 15/10 * 1000/3600
= 15/36 m/s
speed = distance/time
time = distance/speed
time = 9m/15/36m/s
time = 9/1 * 36/15
time = 21.6 seconds
