A person walks up a stationary escalator in time t1. If he remains stationary on the moving escalator, then it can take him up in time t2 . How much time would it take him to walk up the moving escalator.
- \(\frac{t_{1}+t_{2}}{2}\)
- \(\sqrt{t_{1}+t_{2}}\)
- \(\frac{t_{1} t_{2}}{t_{1}+t_{2}}\)
- \(t_{1}+t_{2}\)
Answer
(C) t_ 1 t_ 2 t_ 1 +t_ 2
