Question

Две моторные лодки выехали одновременно навстречу друг другу от двух пристаней, находящихся на расстоянии 462 км друг от друга. Одна двигалась со скоростью 35км.ч,другая-42км.ч. Через сколько часов они встретятся?. Какое расстояние пройдет каждая лодка до встречи?

Answer 1

1)   35+42=77(км/ч)-скорость сближения лодок
2)   462:77=6(ч)-время в пути до встречи
3)   35*6=210(км)-пройдет первая лодка до встречи
4)   462-210=252(км)-пройдет вторая

Answer 2

1)35+42=77(км/ч)-общая скорость
2)462:77=6(ч)-они встретятся.
Ответ:6 ч

Answer 3

To find out when the two motorboats will meet and how far each boat will travel before the meeting, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for the two boats to meet and the distance each boat will travel before the meeting.

Calculation:

The distance between the two piers is 462 km.

Boat 1 is moving at a speed of 35 km/h, and Boat 2 is moving at a speed of 42 km/h.

Let's calculate the time it takes for the two boats to meet:

Time = Distance / Speed

For Boat 1: Time taken by Boat 1 = 462 km / 35 km/h = 13.2 hours

For Boat 2: Time taken by Boat 2 = 462 km / 42 km/h = 11 hours

Therefore, the two boats will meet after approximately 11 hours.

Now, let's calculate the distance each boat will travel before the meeting:

For Boat 1: Distance traveled by Boat 1 = Speed * Time = 35 km/h * 11 hours = 385 km

For Boat 2: Distance traveled by Boat 2 = Speed * Time = 42 km/h * 11 hours = 462 km

Therefore, Boat 1 will travel approximately 385 km before the meeting, and Boat 2 will travel the full distance of 462 km before the meeting.

So, to summarize:

- The two boats will meet after approximately 11 hours. - Boat 1 will travel approximately 385 km before the meeting. - Boat 2 will travel the full distance of 462 km before the meeting.
