Question

От пристани одновременно в противоположеных направлениях вышли две мотррные лодки.Первая шла со скростью 350 м/мин,вторая-250м/мин.На какос расстоянии друг от друга они будут через 2 часа?

Answer 1

350х60=21000м= 21 км/ч - скорость первой
250х60=15000м=15 км/ч - скорость второй
(21+15)х2=76 км
Ответ:76км

Answer 2

Problem Analysis

Two military boats leave a harbor simultaneously in opposite directions. The first boat has a speed of 350 m/min, while the second boat has a speed of 250 m/min. We need to determine the distance between the two boats after 2 hours.

Solution

To find the distance between the two boats after 2 hours, we can use the formula: distance = speed × time.

Let's calculate the distance traveled by each boat after 2 hours:

- The first boat travels at a speed of 350 m/min for 2 hours, so its distance is 350 m/min × 2 hours = 700 m. - The second boat travels at a speed of 250 m/min for 2 hours, so its distance is 250 m/min × 2 hours = 500 m.

Now, let's find the distance between the two boats. Since they are moving in opposite directions, we can add their distances together:

- Distance between the two boats = distance of the first boat + distance of the second boat = 700 m + 500 m = 1200 m.

Therefore, the two boats will be 1200 meters apart after 2 hours.

Answer

The two military boats will be 1200 meters apart from each other after 2 hours.
