Question

В 8 часов 57 минут черепаха Катрина отправилась в путешествие из своего пруда в соседний. В 9 часов 5 минут из этого же пруда в том же направлении отправилась черепаха Виктория и догнала Катрину в 9 часов 29 минут. Найдите, с какой скоростью двигалась Катрина, если известно, что Виктория двигалась со скоростью 8 метров в минуту.

Answer 1

9ч29мин-9ч5мин=24мин ползла Виктория
9ч29мин-8ч57мин=32мин ползла Катрин
8*24=192м проползли черепахи
192:32=6м/мин-скорость Катрин
                              

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 and caught up with Katrina at 9:29. - We need to find Katrina's speed, given that Victoria's speed is 8 meters per minute.

Solution

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

Let's break down the problem into smaller steps: 1. Find the time it took for Victoria to catch up with Katrina. 2. Find the distance traveled by Victoria in that time. 3. Use the distance and time to calculate Katrina's speed.

Step 1: Finding the Time

To find the time it took for Victoria to catch up with Katrina, we can subtract the starting times of both turtles.

The time difference between 9:05 and 8:57 is 8 minutes.

Step 2: Finding the Distance

To find the distance traveled by Victoria, we need to know the time it took her to catch up with Katrina.

The time difference between 9:29 and 9:05 is 24 minutes.

Step 3: Calculating Katrina's Speed

Now that we have the distance traveled by Victoria (which is the same as the distance traveled by Katrina), and the time it took for Victoria to catch up, we can calculate Katrina's speed using the formula: speed = distance / time.

Let's substitute the values into the formula: - Distance = 24 minutes - Time = 8 minutes

Katrina's speed = 24 minutes / 8 minutes = 3 meters per minute.

Therefore, Katrina's speed was 3 meters per minute.

Answer

Katrina's speed was 3 meters per minute.
