Question

Помогите пожалуйста. Очень надо . Туристы прошли по реке на байдарках половину намеченного пути и ещё 9 км. Оставшийся путь они могут пройти на байдарках за 3 часа со скоростью 6 км\ч. Узнай весь путь, который должны были пройти туристы на байдарках.

Answer 1

Пусть х- весь путь, который должны пройти туристы на байдарках;
0,5*х -половина пути
0,5*х=3*6+9
0,5*х=27
х=27 / 0,5
х=54км
Ответ: 54км

Answer 2

2*(6*3+9)=2*(18+9)=2*27=54км - весь путь

Answer 3

Calculation of the Total Distance the Tourists Should Have Covered

To calculate the total distance the tourists should have covered on their kayaks, we need to consider the distance they have already covered and the remaining distance.

According to the information provided, the tourists have covered half of the planned distance and an additional 9 km. Let's denote the total distance they should have covered as D.

The distance covered by the tourists is given by:

Distance Covered = (D/2) + 9 km

We also know that the remaining distance can be covered in 3 hours at a speed of 6 km/h. This can be expressed as:

Remaining Distance = Speed x Time

Substituting the values, we have:

Remaining Distance = 6 km/h x 3 h = 18 km

Since the remaining distance is equal to the total distance minus the distance covered, we can set up the following equation:

Remaining Distance = D - [(D/2) + 9 km]

Simplifying the equation, we get:

18 km = D - (D/2) - 9 km

To solve for D, we can multiply through by 2 to eliminate the fraction:

36 km = 2D - D - 18 km

Simplifying further, we have:

36 km = D - 18 km

Adding 18 km to both sides, we get:

D = 54 km

Therefore, the total distance the tourists should have covered on their kayaks is 54 km.
