Question

70. Попрощавшись, гість вийшов із будинку і пішов стежиною зі швидкістю 70 м/хв. Коли він пройшов 360 м, із будинку вибіг господар з пакунком, який забув гість. Господар біг зі швидкістю 100 м/хв. Через скільки хвилин Господар наздожене гостя?​

Answer 1

Ответ:

12

Пошаговое объяснение:

1) 100 – 70 = 30 (м/хв) – швидкість зближення;

2) 360 : 30 = 12 (хв)

Відповідь: через 12 хвилин господар наздожене гостя.

Answer 2

To solve this problem, we can use the formula: time = distance / speed. Let's calculate the time it takes for the guest to walk 360 meters and the time it takes for the host to catch up.

Calculation for the guest:

The guest walks at a speed of 70 m/min. The distance the guest walks is 360 meters. Using the formula, we can calculate the time it takes for the guest to walk 360 meters: time_guest = distance_guest / speed_guest = 360 m / 70 m/min

Calculation for the host:

The host runs at a speed of 100 m/min. We need to find out how long it takes for the host to catch up to the guest. Since the host starts running after the guest has already walked 360 meters, we need to calculate the time it takes for the host to cover the same distance: time_host = distance_host / speed_host = 360 m / 100 m/min

Now, let's calculate the values:

Calculation:

- For the guest: time_guest = 360 m / 70 m/min

- For the host: time_host = 360 m / 100 m/min

Using these calculations, we can determine how long it will take for the host to catch up to the guest.
