Question

Туристы проплыли на лодке против течения реки 6 км и вернулись обратно . На весе путешествие они затратили 4ч 30мин .Какова собственная скорость лодки, если скорость течения реки 1 км/ч?

Answer 1

Решение
Пусть собственная скорость лодки х км\час, тогда скорость лодки по течению реки равна (х+1) км\ч, против течения реки (х -1) км\час

Answer 2

Calculation of the Boat's Speed

To calculate the boat's speed, we can use the formula:

Speed = Distance / Time

In this case, the distance traveled by the boat against the current is 6 km, and the total time spent on the trip is 4 hours and 30 minutes.

To calculate the boat's speed, we need to convert the time to hours. Since there are 60 minutes in an hour, 30 minutes is equal to 0.5 hours.

Now, let's calculate the boat's speed:

Speed = 6 km / 4.5 hours

Speed = 1.33 km/h

Therefore, the boat's own speed is 1.33 km/h.

Please note that this calculation assumes a constant speed throughout the entire trip and does not take into account any variations in speed due to factors such as wind or current.
