Question

Идут навстречу друг другу Иван-царевич и старичок. Сейчас между ними 2 км 700 м, через 6 минут они встретятся. Какая скорость у каждого, если у Ивана-царевича скорость на 50 м/мин больше, чем у старичка?

Answer 1

У ивана-царевича скорость 1км 500м/мин а у старичка скорость 1км 200м/мин

Answer 2

Problem Analysis

We are given that Ivan-tsarevich and the old man are walking towards each other. The distance between them is 2 km 700 m, and they will meet in 6 minutes. We need to determine the speed of each person, given that Ivan-tsarevich's speed is 50 m/min faster than the old man's speed.

Solution

Let's assume the old man's speed is x m/min. Then Ivan-tsarevich's speed would be x + 50 m/min.

We can use the formula speed = distance / time to calculate the speeds of both individuals.

The distance between them is 2 km 700 m, which is equal to 2,700 m.

The time it takes for them to meet is 6 minutes.

Using the formula, we can calculate the speeds as follows:

For the old man: x = distance / time = 2,700 m / 6 min = 450 m/min.

For Ivan-tsarevich: x + 50 = 450 m/min + 50 m/min = 500 m/min.

Therefore, the old man's speed is 450 m/min and Ivan-tsarevich's speed is 500 m/min.

Answer

The old man's speed is 450 m/min and Ivan-tsarevich's speed is 500 m/min.
