Question

A boy is running on a straight road. He runs 500 towards north in 10 minutes and then turns back and runs 200 meters in 1 minute. Calculate his average speed and average velocity during the whole journey.

Answer 1

Answer:

Distance = 500 m

Time = 10 mins = 600 s

Speed = 500/600 = 0.83333...m/s

Displacement = 500 m - 200 m

Displacement = 300 m

Time = 1 min  = 60 s

Velocity = 300/60 = 5 m/s
