Class: Class 11 Subject: Physics Topic: Motion

: In the above question it is given that:

Speed of the woman = 5 km/hr

Distance between her office and home = 2.5 km

Time Taken = distance / speed

= 2.5/5 = 0.5 h = 30 min

It is given that she covers the same distance in the evening by an auto.

Time Taken = distance / speed

= 2.5/25 = 1/10 = 0.1 h = 6 min
