Question

The length of a platform is 200 meter and the length of a train is 120 meter running with a speed of 60km/h. How much time the train will take to cross the platform ?​

Answer 1

Answer:19.2sec

Step-by-step explanation:

total length will be 200m+120m = 320m

speed =  60 kmph or 60*5/18= 50/3 m/s

time = d/t

        = 320/50/3

        =320*3/50

        =96/5

        =19.2 sec

hope it will help u

Answer 2

Step-by-step explanation:

Speed = 60km/h

length of train = 200m = 0.2 km

length of station = 120m = 0.12 km

Total length = 0.2km + 0.12km = 0.32km

time taken = distance/speed = 0.32km/60km/h

= 0.0053 hr.

=19.08 sec.

hope it helps
