Question

A minibus drives 40.2 kilometre with a constant speed of 67 km per hour and other 77.3 kilometres with a constant speed of 103 kilometre per hour. What is its average speed for the total trip?​

Answer 1

Answer:

Average Speed = 87 KM/HOUR

Step-by-step explanation:

Total Distance = 40.2KM + 77.3 KM

= 117.50 KM

Speed for travelling 40.2 KM = 67KM / Hour

Speed for travelling 77.3 KM = 103KM / Hour

Average Speed = Total Distance / Total Time

Distance D = Speed , v x Time t

So t1 = d1/v1 = 40.2/67 = 0.6

t2 = d2/v2 = 77.3/103 = 0.75

Avearge Speed - 117.5/1.35

= 87.03 which is approx 87 KM/HOUR
