Question

Туристы отправились в путишествие по озеру Им предстояло проплыть 60км.они проплыли на лодке 2ч со скоростью 15 км/ч сколько еще кидометров им предстоит проплыть? решите как уровнение

Answer 1

Пусть Х (км)-осталось проплыть туристам.
тогда (60-Х)км-проплыли туристы за два часа.
Зная,что за 2 часа со скоростью 15 км/ч , туристы проплыли ( 15·2=30), составим уравнение:
       60-Х=30
       Х=60-30
      Х=30(км)- осталось проплыть туристам на лодке.
    Ответ:30км.

Answer 2

Problem Analysis

The tourists have already traveled a distance of 60 km in 2 hours with a speed of 15 km/h. We need to find out how many more kilometers they have to travel.

Solution

To find the remaining distance, we can use the formula:

Distance = Speed × Time

Given that the speed is 15 km/h and the time is 2 hours, we can calculate the distance traveled using the formula:

Distance traveled = Speed × Time

Substituting the given values, we get:

Distance traveled = 15 km/h × 2 hours = 30 km

Since the total distance they need to travel is 60 km, we can find the remaining distance by subtracting the distance traveled from the total distance:

Remaining distance = Total distance - Distance traveled

Substituting the values, we get:

Remaining distance = 60 km - 30 km = 30 km

Therefore, the tourists still have to travel 30 kilometers.

Answer

The tourists still have to travel 30 kilometers.
