Question

A bus covered 250 km in 5h, next 200km in 3h and the last 270km in 6h. what was it's average speed ?​

Answer 1

Answer:

Step-by-step explanation:

1) D= 250 km      T= 5 h

   S= 50 kmph

2) D= 200 km     T= 3 h

   S= 66.6 kmph

3) D= 270           T= 6 h

    S= 45 kmph

Central tendency :

A.M =  161.6 / 3 = 48 kmph

H.M = 3 / 0.02+0.015+0.02 = 54.54 kmph
