Question

Атомная подлодка двигаясь со скоростью 30 км час проходит путь от Мурманска до Архангельска за 27 часов за сколько времени ракетный катер пройдёт это расстояние если его скорость на 15 км час больше чем у подлодки

Answer 1

1) 27 * 30 = 810 м проходит атомная лодка
2) 30 + 15 = 45 км/ч скорость у ракетного катера
3) 810 : 45 = 18 часов пройдет это расстояние ракетный ктер

Answer 2

Calculation of Time for the Rocket Boat to Cover the Distance

To calculate the time it would take for the rocket boat to cover the distance between Murmansk and Arkhangelsk, we need to consider the speed of the submarine and the speed of the rocket boat.

Given: - Speed of the submarine: 30 km/h - Time taken by the submarine to cover the distance: 27 hours - Speed of the rocket boat: 15 km/h faster than the submarine

To find the time taken by the rocket boat, we can use the formula:

Time = Distance / Speed

Let's calculate the distance between Murmansk and Arkhangelsk using the given time and speed of the submarine:

Distance = Speed x Time

Distance = 30 km/h x 27 hours

Distance = 810 km

Now, let's calculate the time taken by the rocket boat to cover the same distance:

Time taken by the rocket boat = Distance / Speed of the rocket boat

Time taken by the rocket boat = 810 km / (30 km/h + 15 km/h)

Time taken by the rocket boat = 810 km / 45 km/h

Time taken by the rocket boat = 18 hours

Therefore, the rocket boat would take approximately 18 hours to cover the distance between Murmansk and Arkhangelsk, assuming its speed is 15 km/h faster than the submarine.

Please note that this calculation is based on the given information and assumes constant speeds throughout the journey.
