Problem Analysis

Маша и Петя живут в одном доме, который находится на расстоянии 1200 м от кинотеатра. Маша пошла в кино со скоростью 80 м/мин. Петя вышел из дома, когда Маша проходила мимо киоска с мороженым, и, идя со скоростью 80 м/мин, догнал Машу у самого входа в кинотеатр. На каком расстоянии от дома находится киоск с мороженым?

Solution

To find the distance of the ice cream kiosk from the house, we need to determine the time it took for Petya to catch up with Masha. Since both Masha and Petya are walking at the same speed, the time it took for Petya to catch up with Masha is the same as the time it took for Masha to reach the cinema.

Let's calculate the time it took for Masha to reach the cinema:

Distance from the house to the cinema = 1200 m Masha's speed = 80 m/min

Using the formula: time = distance / speed, we can calculate the time it took for Masha to reach the cinema:

Time taken by Masha = 1200 m / 80 m/min = 15 min

Since Petya caught up with Masha at the entrance of the cinema, it means that Petya also took 15 minutes to reach the cinema.

Now, let's calculate the distance of the ice cream kiosk from the house. We know that Petya caught up with Masha when she was passing by the kiosk. This means that Petya walked for 15 minutes before catching up with Masha.

Distance traveled by Petya = Petya's speed * Time taken by Petya

Distance traveled by Petya = 80 m/min * 15 min = 1200 m

Therefore, the ice cream kiosk is located at a distance of 1200 meters from the house.

Answer
