Please answer question,
My Family went hiking through a cave. To help us track where we were and make out way back out, we left a trail. We left a light flare every 20 feet of the hike. We hiked 2 miles through the cave before turning back. How many flares did we pick up on the way back out of the cave?
Well there are 5280 feet in a mile so times that by two and the total walked distance is 10,560 feet. So, if you dropped a flare every 20 feet, you'd do (10,560/20=528 flares)
