Question

Две улитки выползли навстречу друг другу. Расстояние между ними состовляет 2м 4дм. Одна движется со скоростью 5см/мин, а вторая - 7см/мин. Сколько времени пройдёт до их встречи? На сколько больше сантиметров проползёт более расторопная улитка?

Answer 1

Расстояние между улитками: 2 м 4 дм = 240 см
1 дм = 10 см
4 дм = 40 см
1 м = 100 см
2 м = 200 см

V1 = 5 см/мин - скорость 1 улитки
V2 = 7 см/мин - скорость 2 улитки

Скорость сближения: 5+7=12 см/мин
Встреча произойдет через: 240 / 12 = 20 мин

S1 = 5*20 = 100 см - проползет 1 улитка
S2 = 7*20 = 140 см - проползет 2 улитка

Answer 2

Calculation of Time and Distance for Snails' Meeting

To calculate the time it takes for the two snails to meet and the distance covered by the faster snail, we can use the formula:

Time = Distance / Speed

Given the following information: - Distance between the snails: 2 meters 4 decimeters (2m 4dm) - Speed of the first snail: 5 centimeters per minute (5cm/min) - Speed of the second snail: 7 centimeters per minute (7cm/min)

Let's calculate the time it takes for the snails to meet and the distance covered by the faster snail.

Calculation:

1. Convert the distance between the snails to centimeters: - 2 meters = 200 centimeters - 4 decimeters = 40 centimeters - Total distance = 200cm + 40cm = 240 centimeters

2. Calculate the time it takes for the snails to meet: - Time = Distance / Speed - Time = 240cm / (5cm/min + 7cm/min) = 240cm / 12cm/min = 20 minutes

3. Calculate the distance covered by the faster snail: - Distance = Speed * Time - Distance = 7cm/min * 20 minutes = 140 centimeters

Answer:

Therefore, it will take 20 minutes for the two snails to meet, and the faster snail will cover 140 centimeters more than the slower snail.
