Question

От одной пристани одновременно отошли две моторные лодки в противоположных направлениях.Одна шла со средней скоростью 250 м/мин,а другая-200 м /мин.На каком расстоянии друг от друга будут лодки через 40 мин?

Answer 1

250*40=10000м одна лодка
200*40=8000 м вторая лодка

10000+8000=18000

Answer 2

250х40=10000 м - пройдет одна лодка 
200х40=8000 м - пройдет вторая лодка 
10000+8000=18000 м - расстояние между лодками через 40 мин

Answer 3

Problem Analysis

Two motorboats are departing from the same dock in opposite directions. One boat is traveling at a speed of 250 m/min, while the other boat is traveling at a speed of 200 m/min. We need to determine the distance between the two boats after 40 minutes.

Solution

To find the distance between the two boats after 40 minutes, we need to calculate the total distance traveled by each boat.

The first boat is traveling at a speed of 250 m/min. Therefore, in 40 minutes, it will cover a distance of 250 m/min * 40 min = 10,000 meters.

The second boat is traveling at a speed of 200 m/min. Therefore, in 40 minutes, it will cover a distance of 200 m/min * 40 min = 8,000 meters.

Since the boats are traveling in opposite directions, the distance between them is the sum of the distances covered by each boat. Therefore, the distance between the two boats after 40 minutes is 10,000 meters + 8,000 meters = 18,000 meters.

Answer

The two boats will be 18,000 meters apart from each other after 40 minutes.
