Answer:
They are 600 feet apart from each other.
Step-by-step explanation:
Since Clay is 400 feet away from ground level, which is 0, that sums up to 400. And Jason is -200 below 0, but in this case it is only asking for how much they are apart, so the negative doesn't apply to this. Now all you need to do is 400+200, which gives you the answer of 600 feet.
