a jogger running at 9 kmph alongside a railway track in 240 meters ahead of the engine of a 120 metres long train running at 45 kmph in the same direction . in how much time will the train pass the jogger ????
Read Solution (Total 4)
-
- Total Distance(d) = 240+120 = 360 meter
Relative speed (s) = 45 - 9 = 36 Kmph = 36*5/18 = 10mps
d = s* t
360 = 10*t
t = 36 seconds - 9 years agoHelpfull: Yes(11) No(7)
- time to pass the jogger is=(120+240)/(45-9)=(360/36)*(18/5)=36 minutes

- d = s* t
360 = 10*t
t = 36 seconds

- Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.
= 36 x 5 m/sec
18
= 10 m/sec.
Distance to be covered = (240 + 120) m = 360 m.
Time taken = 360 sec = 36 sec.
