Question

A scooterist travel a certain distance with speed of 50 kmh and returns back at the starting point with a seed of 40 kmh calculate average velocity​

Answer 1

u = 50 km/hr

v= 40 km/hr

Average velocity = (u+v)/2

= (50+40)/2

= 90/2

= 45 km/hr.

Answer 2

Gone at the speed of 50 kmh

return's at the speed of 40 kmh

x/50+x/4o

9x/200h

hence the average speed of whole journey as 44.44 kilometre
