Question

Q1. A TRAIN PASSES 150 METRE LONG PLATFORM IN15 SECONDS AND IT CROSSES A SIGNAL IN 6 SECONDS. FIND THE LENGTH OF THE TRAIN AND THE SPEED OF THE TRAIN IN KM/HOUR

Answer 1

D1 = 150m

T1 = 15sec

$S1 = \frac{D1}{T1}$

$S1 = \frac{150}{15} = 10m \: per \: sec$

S1 = S2 = 10 m per sec

T2 = 6sec

D2 = Length of the train

D2 = S2 × T2

= 10 × 6

Length of the train = 60m

Speed of train in km per hour = 36km per hr
