Question

Suppose you walk across a room of length 9m with a velocity of 1.5 km/h. Express your velocity in m/s and find the time taken to move across the room

Answer 1

Answer:

Time is 21.63 s or 22s.

Explanation:

Distance = 9 m

Velocity = 1.5 km/hr

i. Velocity in m/s = [1.5*5/18] m/s

= 0.416 m/s

ii. Time = Speed = Distance/Time

= 0.416 = 9/T

= 0.416T = 9

= T = 21.63 s or, 22s

Hope this helps.
