Question

A biker covered 120 km at 40km/hr then 145 km at 58 km/hr and finally 35 km in half an hour.What was his average speed through the trip.

Answer 1

Answer:50kmph

Step-by-step explanation:

Distance 1= 120 km           speed = 40kmph                        

time = distance/speed

        =120/40

        =3 hrs

  Distance 2= 145 km

    speed = 58 kmph        

time = distance/speed

        =145/58

=2.5

Distance 3= 35 km

time taken 0.5hrs

Average speed = Total distance/total time

                          =(120+145+35) /(3+2.5+0.5)

                          =300/6

                           =50kmph(Ans)
