Question

Два пешехода вышли навстречу друг другу и встретились через 3 часа. найти скорость первого пешехода, если скорость второго - 5 км/ч, а расстояние между ними 27 км

Answer 1

27:3=9 км/я скорость сближения
9-5 =4 км/ч скорость второго пешехода

Answer 2

Calculating the Speed of the First Pedestrian

To calculate the speed of the first pedestrian, we can use the formula:

Speed = Distance / Time

Given: - Speed of the second pedestrian = 5 km/h - Distance between the pedestrians = 27 km - Time taken to meet = 3 hours

Using the formula, we can calculate the speed of the first pedestrian:

Speed of the first pedestrian = Distance / Time Speed of the first pedestrian = 27 km / 3 hours Speed of the first pedestrian = 9 km/h

So, the speed of the first pedestrian is 9 km/h.

Explanation

The speed of the first pedestrian can be calculated using the formula for speed, which is distance divided by time. In this case, the distance between the pedestrians is 27 km, and they meet after 3 hours. By dividing the distance by the time, we find that the speed of the first pedestrian is 9 km/h.

This calculation is based on the given information and the formula for speed.
