Question

Поезд длиной 250м двигаясь равномерно прошел мост длиной 350м за 1 минуту. какова скорость поезда

Answer 1

Найдём скорость поезда в м/с: 350/60=5.83м/с
найдём скорость в км/ч:   5.83* 3600= 21000 =21км/ч

Answer 2

Calculating the Train's Speed

To calculate the speed of the train, we can use the formula: speed = distance / time. In this case, the train's total distance is the sum of the length of the train and the length of the bridge, and the time taken is 1 minute.

Using the given lengths: - Length of the train (S1) = 250m - Length of the bridge (S2) = 350m - Total distance (S) = S1 + S2 = 250m + 350m = 600m - Time taken (t) = 1 minute = 60 seconds

We can calculate the speed using the formula: speed = total distance / time

Applying the formula: speed = (S1 + S2) / t speed = (250 + 350) / 60 speed = 600 / 60 speed = 10 m/s

So, the speed of the train is 10 m/s.
