Answer:

The error is that instead of subtracting 60 feet from -1260, the expression adds this quantity.

Step-by-step explanation:

If starting at -1260 feet, and then going down (descending) 60 feet (result of descending 5 feet every minute for 12 minutes), the correct operation is:

-1260 + (-5)(12)= -1260-60= -1320
