Question

a train runs at a speed of 65 km per hour for 2 hours then at a speed of 80 km per hourfor 90 minutes and finally at a speed of 60 km per hour for 45 minutes what is the total distance covered by the train

Answer 1

Answer:

v1 = 60km/hr

t1= 8 hrs

s=v x t

s=60 x 8= 480km

therefore,as the distance is same:

given: t2=6 hrs

s=480 km

therefore,

v=s/t=480/6=80km/hr
