Question

Вирішіть задачу!Плизз! Катер,рухаючсь зі швидкістю 30км/год,пройшов відстань між двома пристанями за 4 години.На шляху у зворотному напрямку він затратив на 1 годину більше.З якою щвидкістю рухався катер у зворотному напрямку?

Answer 1

1) 30*4=120(км)-
2) 4-1=3(год)
3) 120:3=40(км/год)

Answer 2

Problem Analysis

To solve this problem, we need to determine the speed at which the boat traveled in the opposite direction. We are given that the boat traveled a certain distance between two ports in 4 hours at a speed of 30 km/h. On the return journey, it took 1 hour longer. We can use this information to calculate the speed of the boat in the opposite direction.

Solution

Let's assume that the speed of the boat in the opposite direction is x km/h.

On the forward journey, the boat traveled a certain distance in 4 hours at a speed of 30 km/h. Therefore, the distance can be calculated using the formula:

Distance = Speed × Time

So, the distance covered in the forward journey is:

Distance = 30 km/h × 4 hours = 120 km

On the return journey, the boat took 1 hour longer. Therefore, the time taken for the return journey is 4 + 1 = 5 hours.

We know that the distance covered in both directions is the same, which is 120 km. So, we can use the formula again to calculate the speed in the opposite direction:

Speed = Distance / Time

Substituting the values, we get:

x km/h = 120 km / 5 hours = 24 km/h

Therefore, the speed of the boat in the opposite direction is 24 km/h.

Answer

The boat traveled at a speed of 24 km/h in the opposite direction.
