Question

Помогите пожалуйста От одной пристани одновременно отошли две моторные лодки в противоположных направлениях.Одна лодка шла со скоростью 250 метров в минуту ,а другая 200 метров в минуту .На каком расстояние друг от друга будут лодки через 5 минут?

Answer 1

1)250*5=1250м
2)200*5=1000м
3)1250+1000=2250м
ответ:2250

Answer 2

1)250+200=450 м мин ( общая скор )
2) 450•5=2250 м

Answer 3

Problem Analysis

We have two motorboats that start from the same dock and move in opposite directions. One boat is traveling at a speed of 250 meters per minute, while the other boat is traveling at a speed of 200 meters per minute. We need to determine the distance between the two boats after 5 minutes.

Calculation

To find the distance between the two boats after 5 minutes, we need to calculate the distance each boat has traveled in 5 minutes.

The distance traveled by the first boat can be calculated using the formula: distance = speed × time. For the first boat, the speed is 250 meters per minute and the time is 5 minutes. Therefore, the distance traveled by the first boat is: distance_1 = 250 × 5 = 1250 meters.

Similarly, the distance traveled by the second boat can be calculated using the same formula: distance = speed × time. For the second boat, the speed is 200 meters per minute and the time is 5 minutes. Therefore, the distance traveled by the second boat is: distance_2 = 200 × 5 = 1000 meters.

To find the distance between the two boats, we subtract the distance traveled by the second boat from the distance traveled by the first boat: distance_between_boats = distance_1 - distance_2.

Substituting the values we calculated earlier, we have: distance_between_boats = 1250 - 1000 = 250 meters.

Answer

After 5 minutes, the two boats will be 250 meters apart from each other.
