Question

The velocity of train increases uniformly from 20 km per hour 60 kilometre per hour 4 hour the distance travel by train

Answer 1

Answer:

acceleration=v-u/t

                    =60-20/4

                     =10km/h²

v²=u²+2aS

3600=400+2×10×S

3600=400+20S

20S=3200

S=3200/20

 =1600 km

hope it helped and pls mark as brainliest:)
