Question

Ростик і Любчик вирішили покататися на велосипедах. Одночасно вони виїхали зі своїх будинків,відстань між якими 2 км 225 м . Ростик їхав зі швидкістю 240м/хв. Через 5 хв. хлопці зустрілись. З якою швидкістю їхав Любчик

Answer 1

Дізнаємося скільки метрів проїхав Ростик якщо їхав зі швидкістю 240 м на хвилину: S= v*t = 240*5=1080 м = 1,08 км
Тоді порахуємо, скільки треба було проїхати Любчику щоб зустрітися з Ростиком через 5 хвилин: 2,225 км - 1,08 км = 1,145 км = 1145 м
Тепер ми можемо порахувати швидкість Любчика: v = S/t = 1145 м/5хв = 229 м/хв

Answer 2

Problem Analysis

Rostik and Lyubchik are riding bicycles towards each other from their respective houses. The distance between their houses is given as 2 km 225 m. Rostik is traveling at a speed of 240 m/min. After 5 minutes, they meet each other. We need to find the speed at which Lyubchik is traveling.

Solution

To find the speed at which Lyubchik is traveling, we can use the formula:

Speed = Distance / Time

Let's calculate the time it took for Rostik and Lyubchik to meet each other.

The distance between their houses is given as 2 km 225 m. We can convert this distance to meters by multiplying it by 1000 (1 km = 1000 m):

2 km 225 m = (2 * 1000) m + 225 m = 2000 m + 225 m = 2225 m

Rostik is traveling at a speed of 240 m/min. After 5 minutes, Rostik would have traveled:

Speed = Distance / Time 240 m/min = Distance / 5 min Distance = 240 m/min * 5 min = 1200 m

Since Rostik and Lyubchik meet each other, the sum of the distances they traveled should be equal to the distance between their houses:

Distance traveled by Rostik + Distance traveled by Lyubchik = Distance between their houses 1200 m + Distance traveled by Lyubchik = 2225 m

Now, let's solve for the distance traveled by Lyubchik:

Distance traveled by Lyubchik = Distance between their houses - Distance traveled by Rostik Distance traveled by Lyubchik = 2225 m - 1200 m = 1025 m

Finally, we can calculate the speed at which Lyubchik is traveling:

Speed = Distance / Time Speed = 1025 m / 5 min = 205 m/min

Therefore, Lyubchik is traveling at a speed of 205 m/min.

Answer

Lyubchik is traveling at a speed of 205 m/min.
