Question

If a 300 m long train is travelling at a constant
speed, then find the ratio of the time it takes to
cross a pole and a 500 m long bridge.
(b) 3:5
(a) 3:8
(c) 5:6
(d) 5:12
​

Answer 1

Answer:

I am not sure

Step-by-step explanation:

I think it is 3:5

Answer 2

Answer:

Speed = Distance/Time, in this case the train is 300m but let's not consider the trains length for this equation because it is replaced by the bridge's distance. Therefore,

Distance = 200m.

Time = X and Speed =25 m/s

When changing the equation to Distance/Speed= Time

200/25= 8s

The time taken is 8 seconds.
