I really need help!! A scuba diver is swimming at the depth shown, and then swims 0.5 foot toward surface every 3 seconds. What is the location of the scuba diver, relative to the surface, after 15 seconds?

Answer:
2.4
Step-by-step explanation:
We divide 0.5 by 3 giving us approximatly 0.16, we have found the rate of change. Now we multiply 15 by 0.16 equals 2.4.
