A woman starts from her home at 9:00 am walks with a speed of 5 km/h on 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. Choose suitable scales and plot the x-t graph of her motion.
Time taken in reaching the office = Distance / speed = 25 / 5 = 0.5 h
Time taken in returning from office =2.5 / 25 = 0.1 h = 6 min
It means that woman reaches the office at 9:30 am and returns home at 5:06 pm.
