Question

Лыжник шёл на лыжах 15 мин., проходя в минуту 200 метров. Затем он уменьшил скорость на 15 мин. и через 20 минут после этого дошел до базы. Какое расстояние прошел лыжник? решите плиззз

Answer 1

15*200+(200-15)*20=3000+3700=6700 метров=6,7 км

Answer 2

Calculation of the Distance Traveled by the Skier

To calculate the distance traveled by the skier, we need to break down the given information and perform the necessary calculations.

1. The skier initially skied for 15 minutes at a speed of 200 meters per minute. 2. After 15 minutes, the skier reduced their speed. 3. The skier reached the base after 20 minutes at the reduced speed.

Let's calculate the distance traveled step by step:

1. Distance covered in the first 15 minutes: - Time: 15 minutes - Speed: 200 meters per minute - Distance = Time * Speed = 15 minutes * 200 meters per minute = 3000 meters.

2. Distance covered in the next 15 minutes (at the reduced speed): - Time: 15 minutes - Speed: Reduced speed (not provided in the question) - The reduced speed is not provided in the question, so we cannot calculate the exact distance covered during this time.

3. Distance covered in the remaining 20 minutes: - Time: 20 minutes - Speed: Reduced speed (not provided in the question) - The reduced speed is not provided in the question, so we cannot calculate the exact distance covered during this time.

4. Total distance traveled: - The total distance traveled is the sum of the distances covered in the first 15 minutes and the remaining time. - Since we don't have the exact distances covered during the reduced speed periods, we cannot calculate the total distance traveled.

Unfortunately, without the information about the reduced speed, we cannot determine the exact distance traveled by the skier.
