Question

Из 2 городов расстояние между которыми 960 км навстречу друг другу в 8:00 утра вышли два поезда они встретились в 6:00 вечера того же дня найти скорость первого поезда если скорость второго 40 км в час

Answer 1

S=960км
t=10ч
V1=?
V2=40км/ч
Решение:
S2=40*10=400км
S1=960-400=560км
V1=560:10=56км/ч
Ответ: 56км/ч

Answer 2

Calculation of the First Train's Speed

To find the speed of the first train, we can use the formula:

Speed = Distance / Time

Given that the distance between the two cities is 960 km and the two trains meet at 6:00 PM on the same day they started at 8:00 AM, we need to calculate the time it took for the trains to meet.

The time elapsed between 8:00 AM and 6:00 PM is 10 hours. Therefore, the trains took 10 hours to meet.

Now we can calculate the speed of the first train:

Speed of the first train = Distance / Time = 960 km / 10 hours = 96 km/h

So, the speed of the first train is 96 km/h.
