Question

Гибралтарский пролив можно пересечь на яхте за 3 часа,а на судне с подводными крыльями за 2 часа.Какую часть составляет время движения через гибралтарский пролив на судне с подводними крыльями от времени движения на яхте?Скорость какого судна больше?

Answer 1

2:3=2/3 составляет время движения через гибралтарский пролив на судне с подводными крыльями от времени движения на яхте.

скорость судна больше, чем скорость яхты.

Answer 2

Time to Cross the Strait of Gibraltar

To calculate the proportion of time saved by crossing the Strait of Gibraltar on a vessel with underwater wings compared to a yacht, we can use the given time values.

- Time to cross on a yacht: 3 hours - Time to cross on a vessel with underwater wings: 2 hours

To find the proportion of time saved, we can use the formula: \[ \text{Proportion of time saved} = \frac{\text{Time saved}}{\text{Total time}} \]

The time saved is the difference in time between the two vessels, which is 3 hours - 2 hours = 1 hour. The total time taken on the yacht is 3 hours.

Calculation

\[ \text{Proportion of time saved} = \frac{1 \text{ hour}}{3 \text{ hours}} = \frac{1}{3} \]

So, the proportion of time saved by crossing the Strait of Gibraltar on a vessel with underwater wings is 1/3 of the time taken on a yacht.

Speed Comparison

Now, let's compare the speeds of the two vessels.

The speed of a vessel can be calculated using the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Since the distance is constant for both vessels crossing the same strait, we can compare the speeds directly using the given times.

The yacht takes 3 hours to cross, and the vessel with underwater wings takes 2 hours. Therefore, the vessel with underwater wings has a higher speed, as it covers the same distance in less time.

In conclusion, the proportion of time saved by crossing the Strait of Gibraltar on a vessel with underwater wings is 1/3 of the time taken on a yacht, and the speed of the vessel with underwater wings is faster than that of the yacht.
