Question

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

Answer 1

velocity=(3/2)×(5/18)=5/12 m/sec
length=9√2(because across room shortest dist is diameter)
time=9√2/(5/12)=108√2/5=~30.547 sec
