Question

Відомі швидкості двох лижників:першого -15км/год другого 11км/год Через скільки годин вони зустрінуться якщо вирушать назустріч один одному з двох населених пунктів відстань між якими 104 км ?​

Answer 1

Они встретятса через 4 часа (11•4)+(15•4)=44+60=104

Вони зустрінуться через 4 години (11•4)+(15•4)=44+60=104

Answer 2

Calculating the Meeting Time of Skiers

To calculate the time it takes for the two skiers to meet, we can use the formula:

time = distance / relative speed

Where: - *distance* is the distance between the two skiers - *relative speed* is the combined speed at which the skiers are approaching each other

Let's calculate the time it takes for the skiers to meet using the given information.

Given Information

- Speed of the first skier: 15 km/h - Speed of the second skier: 11 km/h - Distance between the two skiers: 104 km

Calculating Relative Speed

The relative speed of the skiers is the sum of their individual speeds, as they are moving towards each other.

Relative speed = 15 km/h + 11 km/h Relative speed = 26 km/h

Calculating Meeting Time

Now, we can use the formula to calculate the meeting time:

time = distance / relative speed

Substituting the values: time = 104 km / 26 km/h time = 4 hours

The two skiers will meet after 4 hours if they set off from two different points towards each other with speeds of 15 km/h and 11 km/h respectively.
