Question

A train runs with 60 kmph and after 2 hours the speed is decreased to half.if it started at 6.00 pm at vja by what time it reaches to hyd which is 300 km away from vja

Answer 1

Initial speed= 60 km/h Travel time= 2 hour Travel distance= 60×2=120 km Remaining distance= 300-120=180 km Now speed= 60/2= 30 km/h (as given in question) Travel time= 180/03= 6 h Total time taken= 2+6=8h So, required time= 6 pm + 8 h= 2 am
