Question

a car moves with the 30 km per hour for half an hour 25 km half for 1 hour and 40 km per hour for 2 hour find its average speed

Answer 1

Total distance covered = 30+25+40=95km

Total time taken = 0.5+1+2=3.5hrs

Average speed = total distance covered/ total time taken

                          = 95/3.5=27.14 km/hr = 27km/hr (approx)
