Answer:
Speed of the woman = 5 km/h
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.
Now, speed of the auto =25 km/h
Time taken = Distance / Speed
= 2.5/25=1/10=0.1 h=6 min
The suitable x-t graph of the motion of the woman is shown in the given figure.
