so , d = (60 x 0.52) + (30 x 0.24)+( 70 x 0.71)

=>d= 88.1 km

here ,total time taken will be

t= 0.52+0.24+0.71 = 1.47 hrs

wkt , average speed = d/t

=> 59.932 = 60 km/hr

total time taken by train = 0.52 + 0.24 + 0.71 = 1.47hrs.

average speed = total distance/total time

= 88.10/1.47

= 59.93Km/hr.
