Answer:
425 ft
Step-by-step explanation:
So the snorkeling was 30 ft BELOW sea level while the hike was 395 ft ABOVE sea level.
Below is negative so 30 ft below is -30
Above is positive so 395 ft above is 395
the difference between 395 and -30 looks like this:
395- (-30)
So you can simplify to get this equation:
395+30
which is 425
So the difference between the snorkel and hike is 425 ft
Hope this helps!
