6 ft above ground.

Step-by-step explanation:

The roller coaster starts from an elevation of + 20 feet from the ground.

Now, it first corns 78 ft, then drops 85 ft.

So, the final elevation will be (20 + 78 - 85) = 13 feet above the ground on the second hill.

Again, it climbs 103 ft. and drops 110 ft. and finally his elevation will be = 13 + 103 - 110 = 6 ft above ground. (Answer)
