A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?
Answer & Solution
Correct Answer:
Option
B
$$\eqalign{
& {\text{Speed}} = {\frac{{240}}{{24}}} \,{\text{m/sec}} = 10\,{\text{m/sec}} \cr
& \therefore {\text{Required}}\,{\text{time}} \cr
& {\text{ = }}\, {\frac{{240 + 650}}{{10}}} \,{\text{sec}}. \cr
& = 89\,sec. \cr} $$
