Pat and Kelly went hiking in the mountains. They started at 9,100 ft. They climbed 1,200 ft the first day, descended 900 ft the second day, and climbed 1,000 ft the third day. On the fourth day they descended 800 ft. What was the average altitude at which they hiked?

Answered by Ms. Sue
9,100 + 1,200 + 1,000 - 900 - 800 = ?

Divide the answer by 4.
Answered by Sandy
Sorry Ms. Sue but I am confused does that include the 9100. I thought the want the average altitude should it be 925.
Answered by Sandy
Take the 9100 and add or subtract each of the numbers one by one. Ex 9100 + 1200 = 10,300
9100-900=8200
9100 + 1000 = 10,100
9100 - 800 = 8300
Add all the sums and divide by 4 = 9225
