Question

Два бегуна на стадионе одновременно начинают бежать противоположных направлениях со скоростью 235 см в секунду и 312 см в сек какое расстояние будете между бегунами через 7 секунд

Answer 1

Значит решаем.

Найдем сколько пробежит первый за 7 секунд: 7*235=1645 см

Найдем сколько пробежит второй за 7 сек: 312 * 7 = 2184.

Т.к. они бежали в противоположные стороны, то складываем расстояние

2184 + 1645=3829 см будет между бегунами через 7 секунд

Answer 2

235+312=547 м/сек скорость удаления.
547*7=3829 м расстояние между бегунами через 7 секунд.
Ответ: 3829 метров.

Answer 3

Calculation of the Distance between the Runners

To calculate the distance between the two runners after 7 seconds, we need to determine the total distance covered by each runner in that time.

Runner 1's speed is 235 cm/s, so in 7 seconds, they would cover a distance of 235 cm/s * 7 s = 1645 cm.

Runner 2's speed is 312 cm/s, so in 7 seconds, they would cover a distance of 312 cm/s * 7 s = 2184 cm.

Now, to find the distance between the two runners, we subtract the distance covered by Runner 1 from the distance covered by Runner 2:

Distance between the runners = Distance covered by Runner 2 - Distance covered by Runner 1 = 2184 cm - 1645 cm = 539 cm.

Therefore, the distance between the two runners after 7 seconds will be 539 cm.
