A bus travels first 20 km in 1h, next 20 km in half an hour and next 20 km in  1h. Calculate the average speed of the bus
Asked by Nimmi | 27 Apr, 2020, 12:42: PM
answered-by-expert Expert Answer
Average speed = total distance travelled/ total time taken 
 
Total distance travelled = 20 + 20 + 20 = 60 km 
 
Total time taken = 1 +0.5 +  = 2.5 h
 
Thus, 
 
A v e r a g e space s p e e d space o f space b u s space equals space fraction numerator 60 over denominator 2.5 end fraction space equals space 24 space k m divided by h
