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.
