Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
Since Hugo climbed his mountain 3 times, he climbed 3*10000=<<3*10000=30000>>30,000 feet.
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.
Since Hugo climbed 30,000 feet, Boris would need to need to climb his mountain 30,000/7500= <<30000/7500=4>>4 times to climb a total of 30,000 feet.
