Question

a car covers a distance of 300 km with an average speed of 60 KMPH and the next 5hrs with an average speed of 80 KMPH.find the average speed​

Answer 1

case -1

time = (300/60)

      = 5 hrs

case-2

distance = (80*5)

              = 400 km

Total distance = (400+300)

                        = 700 km

Total time = (5+5)

                 = 10 hrs

Average speed = (700/10)

                          = 70 km/hr.
