Question

От двух пристаней,расстояние между которыми 350км,в 11ч отправились на встречу друг другу два теплохода.средняя скорость первого-32км/ч,средняя скорость второго 38км/ч.в какое время теплоходы встретятся?

Answer 1

В 16:00 они встретятся. Нашёл так: 350÷(32+38)=5часов
11+5=16 часов

Answer 2

Problem Analysis

We have two ships traveling towards each other from two different ports. The distance between the ports is 350 km. The first ship has an average speed of 32 km/h, and the second ship has an average speed of 38 km/h. We need to calculate the time it takes for the ships to meet.

Solution

To find the time it takes for the ships to meet, we can use the formula:

Time = Distance / Speed

Let's calculate the time for each ship separately and then add them together to find the total time.

1. Time taken by the first ship: - Distance = 350 km - Speed = 32 km/h - Time = Distance / Speed = 350 km / 32 km/h = 10.9375 hours

2. Time taken by the second ship: - Distance = 350 km - Speed = 38 km/h - Time = Distance / Speed = 350 km / 38 km/h = 9.2105 hours

Now, we can add the times together to find the total time:

Total Time = Time taken by the first ship + Time taken by the second ship = 10.9375 hours + 9.2105 hours = 20.148 hours

Therefore, the two ships will meet in approximately 20.148 hours.

Answer

The two ships will meet in approximately 20.148 hours.
