Question

rajesh,while going to school from his home walked 250 metres in one minute. lf he reaches his school in just 5 minutes,then how far is his school from his home​

Answer 1

rajesh Home to school to again home

From home to school distance is 3 km time taken is 30 min = (30/60) hour = 0.5 hour

And in returning from school to home time taken = 20 min = (20/60) hour = 0.33 hour

average speed = Total distance / time taken

= (3 + 3)/(0.5 + 0.33) km/h

= 7.2 km/h
