Question

(f) The distance between the house and the
market is 7.2 km. If a man takes 10min to reach to market, calculate speed in m/s. Also express it is Km/hr.

​

Answer 1

Explanation:

Given, Distance = 7.2 km , Time - 10min

Now distance in meters = 7.2* 1000 = 720.0 m

And time = 10 * 60 = 600 seconds

So speed= distance / time= 720/600= 1.2 m/s and in km/hr = 1.2*3600/1000 = 4.32km/hr
