Answer:
Step-by-step explanation: His final position relative to ground level should be -3. If he starts out 6 feet under ground that is a negative number. So we have -6. Then he climbs up 14 feet. So we are going to add -6+14 which equals 8. Next it says he climbs down 11 feet. So we have a -11 and we will do 8-11=-3.
So -3 is the answer
Hope this helps.
