Answer:

answer is 14 sec

Step-by-step explanation:

1) length of 1st train =200m

speed of 1st train =45km/h

= 45×5/18 = 12.5 m/s

2)length of 2nd train =250m

speed of 2nd train = 50km/h

= 14 m/s

therefore,

the total length =200+250=450m

the total speed = 12.5+14 = 26.5m/s

time = length/Speed

= 450/26.5

= 13.98 = 14

time is 14 sec
