Question

A bus going from Bengaluru to Mysore in 3 hours and return in 3.5 hours.If the distance between Bangalore and Mysore is 150 kilometres then average speed and average velocity of bus is
(1)0km/hr,40km/hr
(2)0km/hr,0km/hr
(3)40km/hr,0km/hr
(4) both will be the same

Answer 1

Answer:

Ans 3 is correct except Avg. speed is wrong

Explanation:

Total distance = 150 × 2 = 300km

Total time = 3 + 3.5 = 6.5

Average Speed = Total distance/Total time = 300/6.5 = 46.2 km/hr (40 km option is wrong)

Distance from B to M = 150 km

Distance from M to B = 150 km

Displacement = 150 - 150 = 0 km

Average Velocity = Total Displacement/Total time = 0/6.5 = 0 km/hr
