Question

Rahul walks to his school which is 500 metre from the house in 10 minutes find average speed if he goes and comes back to and from school in 20 minutes what is his average velocity

Answer 1

speed =distance/time
v=500/10
v=50m/min

Answer 2

when rahul go to school
distance=500m
time=10min convert it into seconds because distance is in metres
time=10×60
=600sec
speed=dis/time
=500/600
=0.833m/s
when he come to home
distance =500m
time =20min
=20×60
=1200sec
speed =distance/ time
=500/1200
=0.0833m/s
