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

• physics -

1.5 km/h is pretty slow walking.

It is 1500 m in 3600 s, which is 0.417 m/s.

Time = Distance/Speed

• physics -

21.582sec

• physics -

Velocity = 3/2 km/h
Concert into m/s = 3/2×5/18= 5/12

Distance travelled = 9m

Time = Distance / Velocity
= 9/5/12
= 9 × 12 / 5 =21.6sec.
