Question

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

Answer 1

hey mate here is your answer

v=1.5km/h=1.5×5/18= 2.5/6m/s.

d=9cm=.9m

t=d/v

=.9×6/2.5

=54/25

=2.8second

it will surely help you.
