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
