to go past the platform 500m long​

Answer 1

x/500 =85/300

x =85×500/300

x=141.6

Answer= a train move to past platform=141.6 km/h

Answer 2

Answer:

200m

Step-by-step explanation:

Time difference while crossing platform and a signal is 30 - 12 = 18s.

=> Train travels 300m in 18s

=> Speed of train = 300/18 x 18/5 = 60 km/hr.

=> Length of train = 300/18 x 12 = 200m.
