Question

a train travels at 60km/h for 0.52hr,30km/h for the next 0.24hr and then 70km/h for the next 0.71 hr. What is the average speed of the trip​

Answer 1

Answer:

here , total dist = speed x time

 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
