Calculation of Remaining Time for the Russian Ship Crew

To calculate the remaining time for the Russian ship crew, we need to consider the following information:

- The crew managed to escape on lifeboats after 18 minutes. - They covered two-thirds (two-fourths) of the distance to the shore.

Let's break down the calculation step by step:

1. Calculate the total time taken to cover two-thirds of the distance: - Since the crew covered two-thirds of the distance in 18 minutes, we can calculate the total time required to cover the entire distance using the proportion: - 18 minutes correspond to two-thirds of the distance. - Let's assume the total time required to cover the entire distance is x minutes. - We can set up the proportion: 18 minutes is to two-thirds as x minutes is to one. - This can be written as: 18 minutes / (2/3) = x minutes. - Solving this proportion, we find that the total time required to cover the entire distance is 27 minutes.

2. Calculate the remaining time for the crew to reach the shore: - Since the crew has already spent 18 minutes, we can subtract this time from the total time required to cover the entire distance: - Remaining time = Total time - Time already spent. - Remaining time = 27 minutes - 18 minutes. - Therefore, the crew has 9 minutes left to reach the shore.
