4. mountain climbing mt. mckinley
in alaska is the highest mountain in
north america at 20,320 feet. a climbing
team starts its ascent from a base camp
at 2000 feet and ascends 15,235 feet. the
team then descends 183 feet before
ascending 398 feet. how many more feet
must the team ascend to reach the
summit?

2870 feet.

Step-by-step explanation:

They start at base camp which is 2000 feet, which means that they only have to climb 20 320 - 2000 feet. That equals 18 320 feet.

2. Then they climb 15 235 feet, which means that they have 18 320 - 15 235 feet left to climb. That equals 3 085 feet.

3. Then they descend 183 feet which means that went down the mountain 283 feet. Therefore they will have 13 085 + 183 feet left to climb. That equals  3 268 feet.

4. finally they climb 398 feet which means that they will have 3 268 - 398 feet left to climb. That equals 2870 feet.
