Question

an oceanographic research vessel comes across a volcano under the sea. The top of the volcano is 450 ft below the surface and the sea floor is -6700 ft. What is the height of the volcano.

I believe it would be -6250ft..is this true

Answer 1

This one is a little tricky, but i w0uld do it this way:

h = -450 -(-6700) =-450 + 6700 = 6250ft

I placed a neg. sign in front of 450 because it is below the surface also.
