Question

в 8 часов расстояние между 2 катерами, плывущими на встречу друг другу, было 250 км. скорости катеров 25км/ч и 35км/ч. стретится ли они до 12 часов тогоже дня

Answer 1

Problem Analysis

We have two boats traveling towards each other. The distance between them is 250 km. The speeds of the boats are 25 km/h and 35 km/h. We need to determine if they will meet before 12:00 PM on the same day.

Solution

To solve this problem, we can calculate the time it takes for the boats to meet by using the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two boats since they are moving towards each other.

Let's calculate the time it takes for the boats to meet:

Relative Speed = Speed of Boat 1 + Speed of Boat 2

Relative Speed = 25 km/h + 35 km/h = 60 km/h

Time = Distance / Relative Speed

Time = 250 km / 60 km/h

Time ≈ 4.17 hours

Since the time it takes for the boats to meet is approximately 4.17 hours, we can determine if they will meet before 12:00 PM.

Conclusion

Based on the calculations, the boats will meet before 12:00 PM on the same day.
