Answer 1

1) 240:80= 3 часа время в пути

2)75 х 3=225 км проехал 2 мотоциклист

3)240+225=465 км расстояние между городами.

Answer 2

1)240:80=3(ч)-время встречи.

2)75*3=225(км)-до встречи второму мотоциклисту.

3)240+225=465(км)-между городами.

Ответ:465км.

Answer 3

Problem Analysis

Two motorcyclists start simultaneously from two different cities and travel towards each other. The first motorcyclist travels at a speed of 80 km/h and covers a distance of 240 km before they meet. 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 it takes for the first motorcyclist to reach the meeting point.

The speed of the first motorcyclist is 80 km/h, and the distance traveled is 240 km. We can use the formula to find the time:

Time = Distance / Speed

Substituting the values, we get:

Time = 240 km / 80 km/h = 3 hours

Now, let's calculate the distance traveled by the second motorcyclist in 3 hours. The speed of the second motorcyclist is 75 km/h.

Distance = Speed × Time = 75 km/h × 3 hours = 225 km

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

Conclusion

The distance between the two cities is 225 km.
