Question

Выберите к задачам нужные уравнения и решите их. Попрыгунья прошла 240 км за 8 часов.Её скорость в 5 раз больше,чем скорость шлюпа.Чему равна скорость шлюпа?

Answer 1

1. 240 : 8 = 30 км/час (скорость попрыгуньи)
2. 30 : 5 =  6 км/час (скорость шлюпа)

Answer 2

Problem Analysis

To solve this problem, we need to find the speed of the boat (шлюпа) given that the jumper (попрыгунья) traveled 240 km in 8 hours and her speed is 5 times greater than the speed of the boat.

Solution

Let's assume the speed of the boat is x km/h. According to the problem, the speed of the jumper is 5 times greater than the speed of the boat, so the speed of the jumper is 5x km/h.

We know that the distance traveled by the jumper is 240 km and the time taken is 8 hours. We can use the formula distance = speed × time to set up an equation for the jumper:

240 = (5x) × 8

Now, we can solve this equation to find the value of x, which represents the speed of the boat.

Calculation

Let's solve the equation:

240 = (5x) × 8

Dividing both sides of the equation by 8:

30 = 5x

Dividing both sides of the equation by 5:

6 = x

Therefore, the speed of the boat (шлюпа) is 6 km/h.

Answer

The speed of the boat (шлюпа) is 6 km/h.

Explanation

The problem states that the jumper (попрыгунья) traveled 240 km in 8 hours, and her speed is 5 times greater than the speed of the boat. By setting up an equation and solving it, we found that the speed of the boat is 6 km/h.
