Question

Туристы прошли по реке на байдарках половину намеченого пути и ещё 9 км. Оставшийся путь они могут пройти на байдарках за 3 ч со скоростью 6км\ч. Узнай весь путь ‚ который должны были пройти туристы на байдарках

Answer 1

1) 3*6=18(км)-осталось пройти туристам.
2) 18+9=27(км)-половина намеченного пути.
3) 27*2=54(км)-длина всего маршрута.
Ответ:54 км

Answer 2

Calculation of the Total Distance

To calculate the total distance that the tourists were supposed to cover on their kayaks, we need to add the distance they have already covered to the remaining distance.

The tourists have already covered half of the planned distance and an additional 9 km. Let's denote the total distance they were supposed to cover as D.

The equation to calculate the total distance is as follows:

D = (1/2)D + 9

Simplifying the equation, we can solve for D:

(1/2)D = 9

D = 9 * 2

D = 18 km

Therefore, the total distance that the tourists were supposed to cover on their kayaks is 18 km.

Calculation of the Remaining Distance

To calculate the remaining distance that the tourists need to cover on their kayaks, we subtract the distance they have already covered from the total distance.

The equation to calculate the remaining distance is as follows:

Remaining Distance = Total Distance - Distance Covered

Substituting the values, we have:

Remaining Distance = 18 km - 9 km

Remaining Distance = 9 km

Therefore, the remaining distance that the tourists need to cover on their kayaks is 9 km.

Calculation of the Time Required to Cover the Remaining Distance

To calculate the time required to cover the remaining distance, we need to divide the remaining distance by the speed at which they can cover the distance.

The equation to calculate the time required is as follows:

Time = Distance / Speed

Substituting the values, we have:

Time = 9 km / 6 km/h

Time = 1.5 hours

Therefore, the time required to cover the remaining distance of 9 km is 1.5 hours.

Summary

The tourists were supposed to cover a total distance of 18 km on their kayaks. They have already covered half of the distance and an additional 9 km. The remaining distance they need to cover is 9 km, and they can cover it in 1.5 hours with a speed of 6 km/h.
