Question
Akash, during his journey, travels for 30 minutes at a
speed of 20 km/h, another 20 minutes at a speed of 30 km/h, and 2 hour at a speed of 40 km/h and 3 hour at a speed of 50 km/h. what is the average velocity?Solution
Total distance = 30/60× 20 + 20/60× 30 + 2× 40 + 3 × 50 = 10 + 10 + 80 + 150 = 250 km Total time = 30/60 + 20/60 + 2 + 3 = 35/6 hr. Average velocity = (Total distance)/(Total time ) = (250 × 6)/35 = 42.85 km/hr.
