Wipro Company Numerical Ability Time Distance and Speed

A man covers a distance on scooter .had he moved 3kmph faster he would have taken 40 min less. If he had moved 2kmph slower he would have taken 40min more.the distance is.

Read Solution (Total 1)

let the distance be x
speed be y
case 1:
speed 3kmph more and time is 40 min less
so
x/y+3=x/y-(40/60)
we get
9x=2y^2+6y
similary
x/y-3=x/y+(40/60)
we get y=12
and x=40 ans....cheers
