IBPS Government Jobs Exams Numerical Ability Time Distance and Speed

A train completes its journey from station X to station Y at a uniform speed and without any stoppage. Had the speed of the train been 24 kmph more,it would have taken 8 hours less to cover the distance.if the station are X and Y are 720 km apart then what is the original speed of the train?

a)24kmph
b)36kmph
c)40kmph
d)48kmph
e)60kmph

Read Solution (Total 4)

(720/x) - (720/(x+24)) = 8
x = 36

dist 720
s=720/x
s+24=720/x-8
Devide both equations
we get x=15
hence ans is 48kmph

go with options: c)

speed =distance / time

t=d/s
720/36=> 20 hrs
new speed = s+24 = > 60
720/60=12

so 20-12= >8 hrs
