Distance = 70 × 0.71 hr . = (31.2 + 7.2 + 49.7) km = 88.1 km . Total time taken = (0.52 + 0.24 + 0.71) hr = 1.47 hr.
Answer is 1.47 hrs

Here is my answer
Total distance covered by train
Distance = speed * time
(60*0.52+30*0.24+70*0.71) =88.1km
total time taken
(0.52+0.24+0.71)=1.47hr
average speed = total distance/total time taken
=88.1/1.47=59.93km/h
