Vedclass · Answer

(C) Let the time taken by the train to pass the jogger be $t$ seconds.Relative speed of the train with respect to the jogger $= 45 - 9 = 36 \; km/hr$.Converting the relative speed to $m/s$: $36 	imes \frac{5}{18} = 10 \; m/s$.The total distance to be covered by the train to completely pass the jogger is the sum of the initial distance between them and the length of the train: $240 \; m + 120 \; m = 360 \; m$.Time taken $t = \frac{	ext{Total Distance}}{	ext{Relative Speed}} = \frac{360 \; m}{10 \; m/s} = 36 \; sec$.

$A$ jogger running at $9 \; km/hr$ alongside a railway track is $240 \; m$ ahead of the engine of a $120 \; m$ long train running at $45 \; km/hr$ in the same direction. In how much time (in $sec$) will the train pass the jogger?
