Question

В 8ч 57мин черепаха Катрина отправилась в путешествие из своего пруда в соседний. В 9ч 5мин из этого же пруда в том же направлении отправилась черепаха Виктория и догнала Катрину в 9ч 29мин. Найдите скорость Катрины если известно что Виктория ползла 8м/мин.

Answer 1

Расстояние   одинаково. определяем время черепахи Виктории
9 ч 29 мин - 9 ч 5 мин = 24 мин
Расстояние
24 мин * 8 = 192 м
Время катрины
9 ч 29 мин - 8 ч 57 мин= 32 мин
Скорость катрины
192 м : 32 мин = 6 м/мин

Answer 2

Problem Analysis

We are given the following information: - At 8:57, a turtle named Katrina started a journey from her pond to a neighboring one. - At 9:05, another turtle named Victoria started from the same pond in the same direction as Katrina. - Victoria caught up with Katrina at 9:29. - We are also given that Victoria's speed is 8 m/min.

We need to find Katrina's speed.

Solution

To find Katrina's speed, we can use the formula: speed = distance / time.

Let's break down the problem into smaller parts:

1. Calculate the time difference between Katrina's start and Victoria's start: - The time difference is 9:05 - 8:57 = 8 minutes.

2. Calculate the time it took for Victoria to catch up with Katrina: - The time difference is 9:29 - 9:05 = 24 minutes.

3. Calculate the distance traveled by Victoria: - Victoria's speed is given as 8 m/min. - Distance = speed * time = 8 m/min * 24 min = 192 meters.

4. Calculate the time it took for Katrina to travel the same distance: - The time difference between Katrina's start and Victoria's catch-up is 8 minutes. - The time it took for Katrina to travel the same distance is 24 minutes + 8 minutes = 32 minutes.

5. Calculate Katrina's speed: - Distance = speed * time. - We know the distance is 192 meters and the time is 32 minutes. - Convert the time to hours: 32 minutes / 60 minutes/hour = 0.5333 hours. - Speed = 192 meters / 0.5333 hours = 360 meters/hour.

Therefore, Katrina's speed is 360 meters/hour.
