**Vipster**, Sunday, October 18, 2009 at 7:02pmNot sure what you exactly want but here is what you will need to get your answers:

V1 - Velocity of the jet

V2 - Velocity of Wind

So 2500km/(V1+V2) = 2.5hrs ----- (1)

2000km/(V1-V2) = 2.5hrs ----- (2)

Solving for the above 2 equations:

2500V1 -2500V2 = 2000V1 + 2000V2

500V1 = 4500V2

or V1 = 9V2

Putting this in (1)

10V2 = 1000

V2 = 100km/hr (Wind)

V1 = 900km/hr (Jet)

Thats the answer
