Answer:
Total distance=108+36+90=234km
Total time=2h+0.5h+1.5h=4h
Average speed = total distance/total time
=234/4
=58.5km/h
So, 58.5km/h is ur answer.

Answer:
The average speed of the train during the whole journey is 52 km/hr.
Step-by-step explanation:
We are given that a train covers 108 km in first two hours, 36 km in next half an hour and 90 km in next two hours.
So, Total distance covered by train = (108 + 36 + 90) km = 234 km
Total time taken by the train = (2 + 0.5 + 2) hr = 4.5 hour
Therefore, Speed of train = (Total distance) ÷ (Total time)
= 234 ÷ 4.5 = 52 km/hr.
Hence, the average speed of the train during the whole journey is 52 km/hr.
