Question

A train 150 m long is running at 72 km/hr. It crosses a bridge in 13 seconds. Find
the length of the bridge.​

Answer 1

Answer:

Explanation:

Hey mate here is your answer:

We can solve using this equation: (length of bridge + length of train) = speed of train * time to cross bridge So: x + 150 = 72km/h * 13s Convert 72km/h to m/s => 72000m/3600s => 20m/s (speed of train) Now, solve: x + 150m = 20m/s *13s => x + 150m = 260m => x = 260m - 150m = 20m/s *13s => x + 150m = 260m => x = 260m - 150m => x = 110m (length of bridge)

Hope it helps you.
