Question

Рас­сто­я­ние между при­ста­ня­ми А и В равно 126 км. Из А в В по те­че­нию реки от­пра­вил­ся плот, а через 1 час вслед за ним от­пра­ви­лась яхта, ко­то­рая, при­быв в пункт В, тот­час по­вер­ну­ла об­рат­но и воз­вра­ти­лась в А. К этому вре­ме­ни плот про­шел 34 км. Най­ди­те ско­рость яхты в не­по­движ­ной воде, если ско­рость те­че­ния реки равна 2 км/ч. Ответ дайте в км/ч.​

Answer 1

Объяснение:

Пусть ско­рость яхты в не­по­движ­ной воде равна х км/ч.       ⇒

Answer 2

This is a math problem related to the motion of a boat and a yacht in a river. To find the speed of the yacht in still water, you can use the following formula:

Speed of Yacht in Still Water = (Speed of Boat Downstream - Speed of River Current)

Here's how you can calculate it:

1. The boat (plow) travels downstream at a speed of 2 km/h (current speed) + 34 km/h (distance traveled) = 36 km/h.

2. The yacht's speed downstream is the same as the boat's speed downstream, which is 36 km/h.

3. The yacht travels upstream at the boat's speed downstream minus the current speed, which is 36 km/h - 2 km/h = 34 km/h.

So, the speed of the yacht in still water is 34 km/h.
