Question

Растояние между городом изимовкой 150 км из города к зимовке выехоли аэоросани идвигались 60 км/ч в это же время из зимовки пошел лыжник со средней скоростью 15 км/ч .на каком растоянии от зимовки он встретил аэросани?

Answer 1

Через два часа.
сани  ехали 60 км в час, а лыжник 15 км в час.
За час они приближались друг к другу на 75 км
150 : 75 = 2 часа

Answer 2

Calculation of the Distance

To calculate the distance at which the skier meets the snowmobile, we need to determine the time it takes for both the snowmobile and the skier to travel the same distance.

Let's denote the distance between the city and Zimovka as D (150 km), the speed of the snowmobile as V1 (60 km/h), and the speed of the skier as V2 (15 km/h).

The time it takes for the snowmobile to travel the distance D is given by the formula:

Time1 = Distance / Speed1

Similarly, the time it takes for the skier to travel the distance D is given by:

Time2 = Distance / Speed2

Since both the snowmobile and the skier start at the same time, we can equate the two times:

Time1 = Time2

Substituting the values, we have:

D / V1 = D / V2

Now, we can solve this equation to find the distance at which the skier meets the snowmobile.

Calculation

Let's calculate the distance at which the skier meets the snowmobile using the given values:

- Distance (D) = 150 km - Speed of the snowmobile (V1) = 60 km/h - Speed of the skier (V2) = 15 km/h

Substituting these values into the equation:

150 / 60 = 150 / 15

Simplifying the equation:

2.5 = 10

Since the equation is not true, it means that the skier and the snowmobile will not meet at any point along the 150 km distance.

Therefore, the skier will not meet the snowmobile on their journey from the city to Zimovka.
