Question

Поезд длиной 750 м, двигаясь равномерно, проезжает мимо светофора за 36 секунд. найдите скорость поезда в км/ч

Answer 1

Ответ:

75 км/ч

Объяснение:

S=750 м=750:1000=0,75 км

t=36 c =36/3600=0,01 ч

V=? км/ч

V=S/t

V=0,75/0,01=75 км/ч

Answer 2

Calculating the Speed of the Train

To find the speed of the train in km/h, we can use the formula:

Speed = Distance / Time

Given: - Length of the train = 750 m - Time taken to pass the traffic light = 36 seconds

First, we need to convert the length of the train from meters to kilometers: - 750 meters = 0.75 kilometers

Now, we can calculate the speed of the train: - Speed = 0.75 km / (36 s / 3600)

Calculation

Using the given values: - Speed = 0.75 / (36 / 3600) - Speed = 0.75 / 0.01 - Speed = 75 km/h

So, the speed of the train is 75 km/h.
