Question

Поезд длиной 120 м движется равномерно по мосту со скоростью 18м/ч. За какое время он пройдет мост, если длина моста равна 240 м?

Answer 1

18км/ч = 5м/с
240 + 120 = 360 метр. длина моста и поезда
t = s/v (360/5)

Answer 2

Calculation of Time to Cross the Bridge

To calculate the time it takes for the train to cross the bridge, we need to use the formula:

Time = Distance / Speed

Given: - Length of the train = 120 m - Speed of the train = 18 m/h - Length of the bridge = 240 m

We can calculate the time it takes for the train to cross the bridge as follows:

Time = (Length of the train + Length of the bridge) / Speed

Substituting the given values:

Time = (120 m + 240 m) / 18 m/h

Simplifying the equation:

Time = 360 m / 18 m/h

Time = 20 h

Therefore, it will take the train 20 hours to cross the bridge.
