Question

Скорость одного лыжника 15 км/ч,а другого - 200м/мин.На сколько болше км он пробегает за 1 час?

Answer 1

200×60=12000м=12км/ч- скорость 2 лыжника
15-12=3км- на сколько больше км он пробегает за 1 час

Answer 2

Calculation of the Difference in Distance Covered

To calculate the difference in distance covered by the two skiers, we need to convert their speeds to the same unit. One skier has a speed of 15 km/h, while the other has a speed of 200 m/min.

Let's convert the speed of the second skier from meters per minute to kilometers per hour:

- 200 meters per minute is equal to 200 * 60 = 12,000 meters per hour. - 12,000 meters per hour is equal to 12,000 / 1,000 = 12 kilometers per hour.

Now that both speeds are in kilometers per hour, we can calculate the difference in distance covered by the two skiers.

The first skier covers 15 kilometers in one hour, while the second skier covers 12 kilometers in one hour.

To find the difference, we subtract the distance covered by the second skier from the distance covered by the first skier:

15 km - 12 km = 3 km.

Therefore, the first skier covers 3 kilometers more than the second skier in one hour.
