Question

PROBLEM 7. Suppose, you walk across a room of length
9 m with a velocity of one and half kilometre per hour.
Express this velocity in unit of m s- and find the time
you will take to move across the room.​

Answer 1

Explanation:

s=9m

u=1/2 km/hr = 1/2×5/18= 0.13888888= 0.14 m/s

time= s/u = 9/0.14= 64.29s
