Answer:
Take total km = 120 km
It taken train for 60km which is half of 120km
Step-by-step explanation:
Time taken in train = 60km/60km/hr = 1 hr
Remaining 60 km
30 km in bus so time taken = 30km / 30 km/hr = 1 hr
30 km in cycle so time taken = 30 km / 10 km/hr = 3 hr
Total time = 1 + 1 + 3 = 5 hr
Total distance / total time = average speed
Average speed = 120 km / 5 hr = 24 km/hr.
