Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 66km/h.
Let the total distance of the journey = 100 km
Distance = 35 km
Time for first segment = 35/70 = 0.5 hours
Distance = 40 km
Time for second segment = 40/80 = 0.5 hours
Remaining Distance = 100 - 35 - 40 = 25 km
Time for remaining distance = 25/50 = 0.5 hours
Total Time = 0.5 + 0.5 + 0.5 = 1.5 hours
Average Speed = 100/1.5 = km/h
Therefore, Anil's average speed for the entire journey is km/h.
