<human>:  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?
<bot>: How many feet is Boris' mountain? ** Boris' mountain has an elevation 2,500 feet shorter than Hugo's mountain, or 10,000-2,500=<<10000-2500=7500>>7500 feet above sea level.
How many feet did Hugo climb? ** If Hugo climbed his mountain 3 times, his total climbing distance would be 3*10,000=<<3*10000=30000>>30,000 feet.
How many times would Boris need to climb his mountain to have climbed the same number of feet as Hugo? ** To climb a total of 30,000 feet, Boris would need to need to climb his mountain 30,000/7,500=<<30000/7500=4>>4 times.
