Locomotive A travels 100km/hr and locomotive B travels 140km/hr. Locomotive B starts 15 kilometers Behind locomotive A and travels on the same direction.
Find the time elapsed and how far each traveled before they meet.

  • Physics -

    v(B)t-v(A)t=15
    t=15/(v(A) –v(B)) = 15/(140-100)=0.375 h = 22.5 min
    s(A) = v(A)t=100•0.375 =37.5 km,
    s(B) = v(B)t=140•0.375=52.5 km
