Question

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

Answer 1

1)200*3=600м

2)240*2=480м

3)600+480+120=1200м=1,2км

Answer 2

Calculation of the Total Distance Run by Slava

To calculate the total distance Slava had to run, we need to add up the distances covered during each segment of his run.

1. In the first segment, Slava ran for 3 minutes at a speed of 200 m/min. Therefore, the distance covered in the first segment is:

Distance 1 = Speed 1 x Time 1 = 200 m/min x 3 min = 600 meters.

2. In the second segment, Slava increased his speed by 40 m/min and ran for 2 minutes. Therefore, the distance covered in the second segment is:

Distance 2 = Speed 2 x Time 2 = (200 m/min + 40 m/min) x 2 min = 480 meters.

3. After completing the first two segments, Slava had 120 meters left to run.

Therefore, the total distance Slava had to run can be calculated by adding the distances covered in each segment and the remaining distance:

Total Distance = Distance 1 + Distance 2 + Remaining Distance = 600 meters + 480 meters + 120 meters = 1200 meters.

Therefore, Slava had to run a total of 1200 meters.
