Sir there is another way to solve this question :- As we know that:- v=u+at 1100km/h = 600km/h + (10km/h.s)t (10km/h.s)t = 1100km/h - 600km/h (10km/h.s)t = 500km/h Now, t = (500km/h) ÷ (10km/h.s) 500km/h 500km h × s = ────── = ──── × ──── 10km/h.s h 10km =50s = So, answer is 50 seconds.

Absolutely right, cancelling the units can also derive the same answer.
