Question

Скорость одного лыжника 15 км/ч, а другого 200м/мин. Насколько скорость больше километров он пробегает за час.

Answer 1

1 км = 1000 метров
15 км/час = 15 * 1000 = 15000 метров/час
200 метров/минут перевести в час = 200 * 60 = 12000 метров/час
15000 м/ч - 12000 м/ч = 3000 м/ч (3000 : 1000) = 3 км/ч
На 3 км/ч больше пробегает

Answer 2

1)200*60=12000(м)=12 (км)-пробегает 2 лыжник за 1 час
2)15-12=3(км)
Ответ: на 3 км

Answer 3

Calculating the Speed Difference

To calculate the difference in speed between the two skiers, we need to convert both of their speeds to the same unit, kilometers per hour (km/h).

- The first skier's speed is 15 km/h. - The second skier's speed is 200 m/min.

First, let's convert the second skier's speed from meters per minute to kilometers per hour: - There are 1000 meters in a kilometer. - There are 60 minutes in an hour.

So, to convert 200 m/min to km/h: - (200 m/min) * (1 km / 1000 m) * (60 min / 1 hour) = 12 km/h.

Now that both speeds are in the same unit, we can calculate the difference.

Speed Difference Calculation

The speed difference is calculated by subtracting the slower speed from the faster speed.

- 15 km/h (first skier's speed) - 12 km/h (second skier's speed) = 3 km/h.

Therefore, the second skier runs 3 kilometers more per hour compared to the first skier.
