Question

A mountain climber starts a climb at an elevation of 380 ft. above sea level. At his first rest stop he has climbed 182 ft., and by his second rest stop he has climbed another 208 ft. It is getting late in the day, so the climber starts his way down the mountain. If the climber descends 235 ft, how much does he need to descend to return to his original starting point?(1 point) Responses
155 feet
78 feet
535 feet
235 feet

Answer 1

To return to his original starting point, the climber needs to descend by the same amount he ascended.

The total amount he ascended is 182 ft + 208 ft = 390 ft.

Therefore, the climber needs to descend 390 ft to return to his original starting point.

Since he has already descended 235 ft, he still needs to descend 390 ft - 235 ft = 155 ft.

Thus, the answer is 155 feet.
