Question

Решите задачу с условием и решением по понятней !!! Лыжник за 3 ч прошел путь длиной 30 км Сколько времени ему потребуется чтобы пройти путь длиной 50 км ? с физическими обозначениями t-время s-пройденый путь и т.д

Answer 1

Находим скорость:V=30:3=10км/ч
теперь время на путь в 50 км:t=50:10=5 ч

Answer 2

Problem Statement

A skier covered a distance of 30 km in 3 hours. How much time will it take for the skier to cover a distance of 50 km?

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

Let's denote the speed of the skier as v (in km/h), the distance covered as s (in km), and the time taken as t (in hours).

According to the given information, the skier covered a distance of 30 km in 3 hours. Therefore, we can write:

v = s / t

Substituting the values, we have:

v = 30 km / 3 hours

Simplifying, we find that the speed of the skier is:

v = 10 km/h

Now, we can use the speed to calculate the time it will take for the skier to cover a distance of 50 km. Rearranging the formula, we have:

t = s / v

Substituting the values, we have:

t = 50 km / 10 km/h

Simplifying, we find that the skier will take:

t = 5 hours

Therefore, it will take the skier 5 hours to cover a distance of 50 km.

Answer

The skier will take 5 hours to cover a distance of 50 km.

Explanation

The skier's speed is calculated by dividing the distance covered by the time taken. In this case, the skier covered a distance of 30 km in 3 hours, resulting in a speed of 10 km/h. Using this speed, we can calculate the time it will take for the skier to cover a distance of 50 km, which is 5 hours.
