the lava in a volcano rest 220 ft below sea level when the volcano erupts the lava shoots 930 ft upward how high does the lava reach before it starts to fall

Respuesta :

930-220= the answer will be the difference between 930 and 220 feet.

The Equation i did for this is  930 + -220= 710, I did a Negative on 220 is Because The Text States that it is "under" The Sea level.
