Question

Длина Большого канала в Венеции 4 км.С его противоположных концов одновременно вышли две гондолы.Скорость одной гондолы 120 м/мин,а другой-130м/мин.Через сколько минут они встретятся?

Answer 1

120+130=250 м/мин скорость сближения
4 000 м : 250 м/мин через столько они встретятся

Answer 2

Calculation of Meeting Time for Gondolas in Venice

To calculate the time it takes for two gondolas to meet in Venice, we need to consider the distance between them and their respective speeds.

Given: - Length of the Grand Canal in Venice: 4 km - Speed of the first gondola: 120 m/min - Speed of the second gondola: 130 m/min

To find the meeting time, we can use the formula:

Meeting Time = Distance / Relative Speed

The relative speed is the difference between the speeds of the two gondolas.

Let's calculate the meeting time step by step:

1. Convert the length of the Grand Canal from kilometers to meters: - 1 km = 1000 m - Length of the Grand Canal = 4 km * 1000 m/km = 4000 m

2. Calculate the relative speed: - Relative Speed = Speed of the second gondola - Speed of the first gondola - Relative Speed = 130 m/min - 120 m/min = 10 m/min

3. Calculate the meeting time: - Meeting Time = Distance / Relative Speed - Meeting Time = 4000 m / 10 m/min = 400 min

Therefore, the two gondolas will meet after 400 minutes.

Please note that the above calculation assumes that the gondolas maintain a constant speed throughout the journey and that there are no other factors affecting their meeting time.
