Question

A car travel at 40km/h for the first third of its journey, at 35km/h for the second third of its journey and at 42 km/ h for the final third of its journey. What is the average speed?​

Answer 1

Answer:

39 km/hr

Explanation:

Given,

Speed 1 = 40 km/hr

Speed 2 = 35 km/hr

Speed 3 = 42 km/hr

Average Speed = (Addition of all Speed)/(No. of Speed)

= (35+40+42)/3 km/hr

= 117/3 km/hr

= 39 km/hr

Hope this helps.
