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 some 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 by 15 meters per minute. 3. The skier continued skiing for an additional 20 minutes at the reduced speed. 4. After 20 minutes at the reduced speed, the skier reached the base.

Let's calculate the distance traveled step by step:

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

2. Distance traveled in the next 20 minutes at the reduced speed: - Speed: 200 meters per minute - 15 meters per minute = 185 meters per minute - Time: 20 minutes - Distance = Speed * Time = 185 * 20 = 3700 meters

3. Total distance traveled: - Distance in the first 15 minutes + Distance in the next 20 minutes = 3000 meters + 3700 meters = 6700 meters

Therefore, the skier traveled a total distance of 6700 meters.
