Jericho is roughly 15–40 kilometers from Jerusalem depending on the exact route and starting/ending points you choose. The most commonly cited practical distances are about 40 kilometers (roughly 25 miles) by road between Jericho and Jerusalem, though shorter air-distance figures around 22–23 kilometers can be quoted for direct line measurements to the nearest points. If you specify whether you need road travel distance, walking distance, or straight-line distance between specific neighborhoods or landmarks, I can give a more precise figure for that route.
