A sailplane has a best glide ratio of 23:1. How many feet will the glider lose in 8 nautical miles?

Explanation:
A best glide ratio of 23:1 means you travel 23 units horizontally for every 1 unit of altitude you lose. So for 8 nautical miles, first convert to feet: 8 NM × 6,076 ft/NM ≈ 48,608 feet. The altitude lost is 48,608 ÷ 23 ≈ 2,113 feet, which rounds to about 2,100 feet. The other options don’t match 8 NM with a 23:1 ratio (e.g., 1,800 ft would imply ≈6.8 NM, 2,500 ft ≈9.45 NM, etc.).
