Question

Можете решить с формулами?: Два парохода плывут навстречу друг другу. Скорости пароходов 32 км/ч и 27км/ч. Сейчас между ними 354 км. Вопросы: а)Какое расстояние будет между пароходами через 2 часа? б)Через сколько времени они встретятся? Пожалуйста помогите мне

Answer 1

354 км- (32 км/ ч*2+27 км/ ч*2)=354 км- (64 км+ 54 км)= 354 км- 118 км=236 км расстояние между пароходами через 2 часа.
354 км: (32 км/ ч+27 км/ ч)= 354 км: 59 км/ ч = 6 ч через 6 ч встретятся пароходы.

Answer 2

Problem Analysis

We have two steamboats traveling towards each other. The speeds of the steamboats are given as 32 km/h and 27 km/h, and the initial distance between them is 354 km. We need to find the distance between the steamboats after 2 hours and the time it takes for them to meet.

Solution

To find the distance between the steamboats after 2 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance between the steamboats after 2 hours:

Distance = (Speed of Steamboat 1 + Speed of Steamboat 2) × Time

Distance = (32 km/h + 27 km/h) × 2 hours

Distance = 59 km/h × 2 hours

Distance = 118 km

Therefore, the distance between the steamboats after 2 hours will be 118 km.

To find the time it takes for the steamboats to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed of the steamboats can be calculated by adding their speeds:

Relative Speed = Speed of Steamboat 1 + Speed of Steamboat 2

Relative Speed = 32 km/h + 27 km/h

Relative Speed = 59 km/h

Now, let's calculate the time it takes for the steamboats to meet:

Time = Distance / Relative Speed

Time = 354 km / 59 km/h

Time = 6 hours

Therefore, it will take 6 hours for the steamboats to meet.

Summary

To summarize: - The distance between the steamboats after 2 hours will be 118 km. - The steamboats will meet after 6 hours.
