Question

В первый день турист прошёл 24 км а во второй на 12 км больше Всего он был в 15 часов Сколько времени шёл турист в каждый из этих дней если он шёл с постоянной скоростью

Answer 1

1) 24+12=36км во 2 день,

2) 36+24= 60 км за 2 дгя

3) 60:15=4 км в час

4 24:4= 6 часов

5) 36:4=9

Answer 2

В первый день турист прошёл 24 км а во второй 12 км + 24 км = 36 км. Всего он прошел 36 км+ 24 км = 60 км, т.е. S = 60, t = 15 и надо найти скорость V. По формуле S = V · t, откуда V = S : t = 60 : 15 = 4 км/ч. В первый день турист шёл S : V = 24 : 4 = 6км, а во второй - 36 : 4 = 9км.

Answer 3

Calculation of Time Taken by the Tourist

To calculate the time taken by the tourist on each day, we need to determine the speed at which the tourist was walking. Since the tourist walked at a constant speed, we can use the formula:

Speed = Distance / Time

Let's calculate the time taken by the tourist on each day.

1. On the first day, the tourist walked 24 km. 2. On the second day, the tourist walked 12 km more than the previous day, which means the distance covered on the second day is 24 + 12 = 36 km. 3. The total time taken by the tourist on both days is 15 hours.

Let's calculate the time taken on each day using the formula mentioned above.

1. First day: - Distance: 24 km - Speed: Unknown - Time: Unknown

2. Second day: - Distance: 36 km - Speed: Unknown - Time: Unknown

To find the speed, we can set up the following equation using the total time taken:

24 km / Speed + 36 km / Speed = 15 hours

Simplifying the equation:

60 / Speed + 90 / Speed = 15

Combining like terms:

150 / Speed = 15

Solving for the speed:

Speed = 150 / 15 = 10 km/h

Now that we have the speed, we can calculate the time taken on each day.

1. First day: - Distance: 24 km - Speed: 10 km/h - Time: 24 km / 10 km/h = 2.4 hours

2. Second day: - Distance: 36 km - Speed: 10 km/h - Time: 36 km / 10 km/h = 3.6 hours

Therefore, the tourist walked for 2.4 hours on the first day and 3.6 hours on the second day.

In summary: - On the first day, the tourist walked for 2.4 hours. - On the second day, the tourist walked for 3.6 hours.

Please note that the above calculations assume a constant walking speed throughout the entire journey.
