Question

Слава бежал 3 минуты со скоростью 200м/ мин, затем он увеличил скорость на 40 м/мин и бежал еще 2 мин.После этого ему осталось пообедать 120м.Сколько всего метров надо было пробежать Славе?

Answer 1

3*200=600
2*240=480
480+600=1080
1080+120=1200

Answer 2

Calculation of the Total Distance Slava Needed to Run

To calculate the total distance Slava needed to run, we need to consider the different segments of his run and add them together.

1. Slava ran for 3 minutes at a speed of 200 m/min. 2. Then, he increased his speed by 40 m/min and ran for another 2 minutes. 3. After that, he had 120 m left to run.

Let's calculate the total distance:

1. Distance covered in the first segment: 3 minutes * 200 m/min = 600 meters. 2. Distance covered in the second segment: 2 minutes * (200 m/min + 40 m/min) = 480 meters. 3. Remaining distance after the second segment: 120 meters.

To find the total distance, we add the distances from each segment:

Total distance = 600 meters + 480 meters + 120 meters = 1200 meters.

Therefore, Slava needed to run a total distance of 1200 meters.
