Answer: C) 264 meters
===========================================================
Step-by-step explanation:
Draw a vertical number line. Mark the values 248, 0, and -16 on the number line. The negative value is to indicate it is below 0, while the positive number is above 0.
The distance from 248 to 0 is 248 units. Let A = 248.
The distance from 0 to -16 is 16 units. Let B = 16
The total distance mentioned so far is A+B = 248+16 = 264
So basically if we start at the highest point (248) and go to the ground level, we traveled 248 meters. Then we travel another 16 meters to go from ground level to the lowest point (-16) leading to a total of 248+16=264 meters in total distance from highest to lowest point.
