Lizzy: Hugo's mountain has an elevation of 10,000 feet above sea level. Boris' mountain has an elevation that is 2,500 feet shorter than Hugo's mountain. If Hugo climbed his mountain 3 times, how many times would Boris need to climb his mountain to have climbed the same number of feet as Hugo?.
Me: Hmmm, let me think. I think this is the detailed solution:
Boris' mountain has an elevation 2,500 feet shorter than Hugo's mountain, or 10,000 - 2,500 = 7500 feet above sea level. If Hugo climbed his mountain 3 times, his total climbing distance would be 3 * 10,000 = 30,000 feet. To climb a total of 30,000 feet, Boris would need to need to climb his mountain 30,000 / 7,500 = 4 times. Final answer: 4.
