A man travels from A to B at a speed of 36 km/hr in 74 minutes and he travels a distance from B to C with a speed of 45 km/hr in 111 minutes.
Formula used:
Average speed = Total distance/Total time taken
Calculation:
Time taken = 74 min : 111 min [given]
Ratio of Time taken = 2 : 3
Average Speed = \(\frac{{36\ \times\ 2\ +\ 45\ \times\ 3}}{{2\ +\ 3}}\)
Average Speed = 207/5
Average Speed = 41.4 km/hr
∴ The average speed of whole journey is 41.4 km/h
