Question

Два мотоциклиста выехали одновременно навстречу друг другу . Первый проехал до встречи 240 км со скоростью 80 км/ч . Скорость второго 75 км/ч . чему равно расстояние между городами

Answer 1

240:80=3 ч до встречи ехал первый
75*3=225 км проехал до встречи второй
240+275=515 км расстояние между городами.

Answer 2

1) 240 : 80 = 3(час) до встречи проехал первый
2) 75 * 3 = 225(км) до встречи проехал второй
3) 240+225=465(км) расстояние между городами

Answer 3

Problem Analysis

We are given that two motorcyclists start simultaneously and travel towards each other. The first motorcyclist travels 240 km at a speed of 80 km/h, while the second motorcyclist travels at a speed of 75 km/h. We need to find the distance between the two cities.

Solution

To find the distance between the two cities, we can use the formula:

Distance = Speed × Time

Let's calculate the time taken by each motorcyclist to reach the meeting point.

The time taken by the first motorcyclist is given by:

Time taken by first motorcyclist = Distance / Speed = 240 km / 80 km/h = 3 hours

The time taken by the second motorcyclist is given by:

Time taken by second motorcyclist = Distance / Speed = Distance / 75 km/h

Since both motorcyclists start simultaneously and meet at the same point, the total time taken by both motorcyclists is the same. Therefore, we can equate the time taken by the first motorcyclist to the time taken by the second motorcyclist:

3 hours = Distance / 75 km/h

To find the distance, we can rearrange the equation:

Distance = 3 hours × 75 km/h = 225 km

Therefore, the distance between the two cities is 225 km.

Answer

The distance between the two cities is 225 km.
