Question

Скорость аэросаней в 4 раза больше скорости лыжника за 3 часа аэросани прошли 168 км сколько километров пройдет за это же время лыжник

Answer 1

168 : 3 = 56 км/ч скорость аэросаней
56 : 4 = 14 км/ч скорость лыжника
14 × 3 = 42 км пройдёт лыжник за это время

Answer 2

Calculation of Distance Covered by the Skier

To calculate the distance covered by the skier in the same amount of time, we can use the given information that the speed of the snowmobile (aerosani) is 4 times greater than the speed of the skier. Additionally, we know that the snowmobile covered a distance of 168 km in 3 hours.

Let's denote the speed of the skier as S and the speed of the snowmobile as 4S (since it is 4 times greater). The time taken by both the skier and the snowmobile is the same, which is 3 hours.

We can use the formula:

Distance = Speed × Time

For the snowmobile, the distance covered is 168 km, the speed is 4S, and the time is 3 hours. Therefore:

168 km = (4S) × 3 hours

To find the distance covered by the skier, we need to solve for S. Let's rearrange the equation:

S = (168 km) / (4 × 3 hours)

Simplifying further:

S = 14 km/h

Therefore, the speed of the skier is 14 km/h. Now, we can calculate the distance covered by the skier in 3 hours using the skier's speed:

Distance = Speed × Time = 14 km/h × 3 hours = 42 km

So, the skier will cover a distance of 42 km in the same amount of time as the snowmobile covered 168 km.

Answer:

The skier will cover a distance of 42 km in the same amount of time that the snowmobile covered 168 km.
