Question

3. A train travelling at 120km/h goes through a tunnel 155m long. Calculate in seconds the time a passenger on train spend in the tunnel ​

Answer 1

To calculate the time a passenger on the train spends in the tunnel, we need to convert the speed of the train to meters per second (m/s) and then use the formula time = distance/speed.

First, let’s convert 120 km/h to m/s: 120 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 33.33 m/s.

Now we can use the formula time = distance/speed to calculate the time a passenger on the train spends in the tunnel: time = 155 m / 33.33 m/s ≈ 4.65 s.

So a passenger on the train spends approximately 4.65 seconds in the tunnel.
