Question

a train traveling at a speed of 60kmph passes a pole in 9 sec .what time it will take to cross a platform, 250mts long

Answer 1

Speed = 60km/h or 60×1000/60×60 = 50/3 m/s

Time taken = 9s

distance travelled = 50/3 × 9 = 150m

D = 250m
T = ?
S = 50/3 m/s

T = D/S
T = 250/50/3
T = 750/50
T = 75/5 = 15s
