Solution

The correct option is A $6$ hrs $21$ min
Distance=600 km
Speed=100 km/hr
Time $= \frac{600}{100} = 6 h r$
Number of stops in 600 km $= (\frac{600}{75}) - 1 = 7$
Time of stopping after every 75 km=3 min
Total time of stopping $= 7 \times 3 = 21 m i n$
Total time to cover 600 km is 6 hr 21 min.
