Question

Суботним утром школьники отправились в лес,где собрались изучать жизнь рыжих лесных муравьев.Они прошли 2I5 расстояние от школы до леса за 2 часа,шагая со скоростью 3 км/ч,потом они утроили 15-дцати минутный привал и прошли оставшиеся расстояние с той же скоростью.Сколько времения заняла дорога в лес?

Answer 1

1) 3*2=6 (км) - прошли до леса и это 2/5 часть всего пути, тогда весь путь: 

2) 6*5/2=15 (км)

3) 15-6=9 (км) - оставшееся расстояние

4) 9:3=3 (часа) - время, за которое прошли оставшееся расстояние

5)  2+3=5 (часов)  заняла дорога в лес, а если с учетом привала, то 5ч15мин.

Answer 2

Calculation of Time Taken to Reach the Forest

To calculate the time taken to reach the forest, we need to consider the distance covered and the speed at which the students were walking.

The students walked a distance of 215 km from the school to the forest. They walked at a speed of 3 km/h for the first part of the journey. After a 15-minute break, they continued walking the remaining distance at the same speed.

Let's calculate the time taken for each part of the journey and then add them together to find the total time taken.

1. Time taken for the first part of the journey: - Distance: 215 km - Speed: 3 km/h - Time = Distance / Speed = 215 km / 3 km/h = 71.67 hours

2. Time taken for the second part of the journey: - Distance: Remaining distance after the break - Speed: 3 km/h - Time = Distance / Speed

To calculate the remaining distance, we subtract the distance covered in the first part from the total distance: Remaining distance = Total distance - Distance covered in the first part Remaining distance = 215 km - 215 km = 0 km

Since the remaining distance is 0 km, the time taken for the second part of the journey is 0 hours.

Now, let's add the time taken for both parts of the journey to find the total time taken:

Total time taken = Time taken for the first part + Time taken for the second part Total time taken = 71.67 hours + 0 hours = 71.67 hours

Therefore, the total time taken to reach the forest is approximately 71.67 hours.

Please note that the given information does not specify the units for the time taken. It is assumed to be in hours based on the given speed in km/h.
