Question

Metro train 150 long is moving at a speed of 45 km per hour how long will it take to pass up metro rail signal

Answer 1

Answer:

12 sec

Step-by-step explanation:

To cross signal train should cover its own length

so here we have give that length of train is 150 m

and speed is 45 km/h

in m/s = 45÷ 3.6 = 12.5 m/s

so now we know the speed of train

Time to cross will be = 150m / 12.5 m/s

= 12 sec

Answer 2

Answer:

12 second

Step-by-step explanation:

(distance ×18)/(speed ×5)=Time (in second)

(150×18)/(50×5)=12
