Question

A woman starts from her home at 9.00 am, walks with a speed of 5 km h^–1 on a straight road up to her office 2.5 km away, stays at the office up to 5.00 pm, and returns home by an auto with a speed of 25 km h^–1. Choose suitable scales and plot the x-t graph of her motion.

Answer 1

Speed of the woman = 5 km/h
Distance between her office and home = 2.5 km

It is given that she covers the same distance in the evening by an auto. Now, speed of the auto = 25 km/h

The suitable x-t graph of the motion of the woman is shown in the given figure.
