Question

От одной пристани одновременно в противоположных направлениях отошли две моторные лодки . одна шла со скоростью 250 метров в минуту, а другая со скоростью 200 метров в минуту. на кком расстоянии друг от друга лодки будут через 4 минуты ?

Answer 1

1) (250+200)×4 =1800(м) - расстояние
Ответ : расстояние между лодками за 4 минуты, будет равно 1800 метрам.

Answer 2

1)250*4=1000(м.)-пройдет первая моторная лодка.
2)200*4=800(м.)-пройдет вторая.
3)1000+800=1800(м.)
Ответ: через 4 минуты лодки будут на расстоянии 1800 метров друг от друга.

Answer 3

Problem Analysis

We have two motorboats that depart from the same dock simultaneously but in opposite directions. One boat travels at a speed of 250 meters per minute, while the other boat travels at a speed of 200 meters per minute. We need to determine the distance between the two boats after 4 minutes.

Solution

To find the distance between the two boats after 4 minutes, we can calculate the total distance covered by each boat and then subtract one from the other.

Let's calculate the distance covered by the first boat in 4 minutes. We can use the formula:

Distance = Speed × Time

For the first boat: - Speed = 250 meters per minute - Time = 4 minutes

Therefore, the distance covered by the first boat in 4 minutes is:

Distance1 = 250 meters/minute × 4 minutes

Now let's calculate the distance covered by the second boat in 4 minutes. Using the same formula:

For the second boat: - Speed = 200 meters per minute - Time = 4 minutes

Therefore, the distance covered by the second boat in 4 minutes is:

Distance2 = 200 meters/minute × 4 minutes

To find the distance between the two boats, we subtract the distance covered by the second boat from the distance covered by the first boat:

Distance between the boats = Distance1 - Distance2

Let's calculate the distances:

Distance1 = 250 meters/minute × 4 minutes = 1000 meters

Distance2 = 200 meters/minute × 4 minutes = 800 meters

Distance between the boats = 1000 meters - 800 meters = 200 meters

Therefore, the two boats will be 200 meters apart after 4 minutes.

Answer

The two motorboats will be 200 meters apart from each other after 4 minutes.
