To calculate the average speed, divide the total distance by the total time. For a 3000-meter course completed in 4 minutes (which is 240 seconds), the average speed is 3000 meters / 240 seconds = 12.5 meters per second. Therefore, the average speed for the course is 12.5 m/s.

Assuming he keeps up the same average speed: the distance is 3000m / 2000m = 1 1/2 times as far, so it will take him 1 1/2 times as long, namely 25 x 1 1/2 = 37 1/2 minutes = 37 minutes 30 seconds.

The downhill skiers' approximate average speed for the 35,000 m course can be calculated by converting the time to seconds (130 seconds) and dividing distance by time. Average speed ≈ 35,000 m / 130 s ≈ 269.23 m/s.

To find the average speed, divide the distance by the time. The distance is 3500 meters and the time is 2 minutes and 10 seconds, which is 130 seconds. Thus, the average speed is approximately ( \frac{3500 \text{ m}}{130 \text{ s}} \approx 26.92 \text{ m/s} ).
