Question

лыжники двигаясь со скоростью 12 километров час прошел расстояние от деревни до железнодорожной станции за 3 часа на обратном пути ему понадобилось 4 часа С какой скоростью шел лыжник на обратном пути

Answer 1

S=V*t1)12*3=36(км)- S пути 2)36/4=9(км/ч)Ответ: V на обратный путь= 9 км/ч.

Answer 2

Calculation of the Skier's Speed

To determine the speed of the skier on the return trip, we can use the formula:

Speed = Distance / Time

Given that the skier traveled a distance from the village to the train station in 3 hours at a speed of 12 kilometers per hour, we can calculate the distance using the formula:

Distance = Speed * Time

Substituting the given values, we have:

Distance = 12 km/h * 3 hours = 36 kilometers

On the return trip, the skier took 4 hours to cover the same distance. To calculate the speed on the return trip, we can use the formula:

Speed = Distance / Time

Substituting the values, we have:

Speed = 36 kilometers / 4 hours = 9 kilometers per hour

Therefore, the skier's speed on the return trip was 9 kilometers per hour.
