?
The length of a train and that of a platform are equal. If with a speed of 90 km/hr the train crosses the platform in one minute, then the length of the train (in meters) is ?
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{
& {L_t} = {L_P} = l \cr
& S = {\text{90 km /hr }} \cr
& \,\,\,\,{\text{ = }}\frac{{90 \times 1000}}{{60}}{\text{ m/min}} \cr
& \,\,\,\,\, = 1500\text{ m/min} \cr
& \Rightarrow l = {L_t} = {L_P} = \frac{{1500}}{2} = 750{\text{ meters}} \cr} $$
