Sarah climbed 3,450 feet of the way up Pikes Peak and then stopped to rest. After she stops, she continues to climb at a rate of 75 feet per hour for h hours. Which expression indicates her elevation, in feet, h hours after she stops? A. 3,450 : 75 * h B. 3,450 - 75 * h C. 3,450 + 75 * h D. (3,450 + 75) : h Reset Submit

Option B

The expression indicates her elevation, in feet, h hours after she stops is given is 3450 - 75h

Solution:

Given that,

Sarah climbed 3,450 feet of the way up Pikes Peak and then stopped to rest

After she stops, she continues to climb at a rate of 75 feet per hour for h hours

Let "h" be the number of hours

If she climbs at 75 feet per hour,

Then for "h" hours, she climbs 75h feet

Already she climbed 3450 feet

The expression indicates her elevation, in feet, h hours after she stops is given by:

⇒ Already climbed feet - after stop climbed feet for "h" hours

⇒ 3450 - 75h

Thus the expression is found
