Walter fell from the eighth platform of some scaffolding and fell past David after falling 4 meters. If he fell for an additional three more times that depth before hitting the ground, and the platforms are evenly spaced out in height, what platform was David on?
Thoughts? Step-by-step reasoning:
Walter fell 4 meters and an additional three times that depth which is 3 * 4 = 12 meters. He fell for a total of 4 + 12 = 16 meters. The eighth platform is 16 meters high and the platforms are evenly spaced so each platform is 16 / 8 = 2 meters high. David was located 4 meters below the 16 meter level which is 16 - 4 = 12 meters high. Each platform is 2 meters high so 12 meters would mean the 12 / 2 = 6th platform.
Thus, the answer is 6.
