Question

Два велосипедиста выехали на встречу друг другу в 10 ч утра и встретились в 13 ч. Сколько времени был в пути каждый велосипедист? Какое расстояние было между ними превоначально , если один велосипедист ехал со скорость 16 км/ч ,а другой - 18 км /ч . пожалуйста можно проверку к этой задаче. решение есть. )

Answer 1

В пути оба были с 10 до 13, т.е. 3 часа.
Скорость сближения равна 18 + 16 = 34
34 * 3 = 102 км.
Проверка.
16 * 3  = 48 - проехал один, 18 * 3 = 54 - проехал другой.
48 + 54 = 102 - между ними совпало, все верно

Answer 2

Problem Analysis

We have two cyclists who start their journey at 10:00 AM and meet each other at 1:00 PM. We need to determine the time each cyclist spent on the road and the initial distance between them. One cyclist travels at a speed of 16 km/h, while the other travels at a speed of 18 km/h.

Solution

To find the time each cyclist spent on the road, we can subtract the start time from the meeting time. The initial distance between the cyclists can be calculated by multiplying the speed of one cyclist by the time it took for them to meet.

Let's calculate the time and distance for each cyclist.

Time Calculation

The cyclists started at 10:00 AM and met at 1:00 PM. To find the time spent on the road, we subtract the start time from the meeting time.

Time spent on the road = Meeting time - Start time

Time spent on the road = 1:00 PM - 10:00 AM

To subtract the times, we need to convert them to a 24-hour format. 1:00 PM is equivalent to 13:00, and 10:00 AM is equivalent to 10:00.

Time spent on the road = 13:00 - 10:00

The time spent on the road is 3 hours.

Distance Calculation

To calculate the distance between the cyclists, we multiply the speed of one cyclist by the time spent on the road.

Distance = Speed * Time

For the first cyclist, who travels at a speed of 16 km/h:

Distance = 16 km/h * 3 hours

The distance traveled by the first cyclist is 48 km.

For the second cyclist, who travels at a speed of 18 km/h:

Distance = 18 km/h * 3 hours

The distance traveled by the second cyclist is 54 km.

Summary

Based on the given information, each cyclist spent 3 hours on the road. The initial distance between them was 48 km for the first cyclist and 54 km for the second cyclist.
