Answer 1

Answer:

Step-by-step explanation:

It takes 18 seconds to cross the bridge by train.

Here is how,

The train is 300 meter long and the bridge is 60 meter long it results 360 meters in total distance travel by the engine of train to cross whole train by that bridge.

Length of train=300m

Length of bridge =60m

=>300+60=360m

Then the speed of train is 72km/hr

Which is 20m/sec.

Therefore, 360/20 = 18

Hence, it takes 18 seconds to travel the distance of 360meter with constant speed of 20m/sec.
