Answer:

40 seconds

Step-by-step explanation:

Answer 2

Step-by-step explanation:

speed of train in m/s = 45 × 5/18 = 12.5m/s

To completely cross the bridge, train has to move (500m + length of the train itself)

So, distance moved by train = 500+150 = 650m

Now, apply Time = Distance / Speed

From the above equation, Time taken by train to cross the road = 650m ÷ 12.5m/s

= 52 seconds
