A submarine dove 35 feet per hour for 7 hours. How deep is the submarine if it originally started at 107 feet below sea level?

Question

Started out -107 feet below

Is diving down 35 feet per hour for 7 hours.

How deep is it now?

Answer 1

the submarine will be 35 * 7 = 245 feet deeper than when it started diving

if we add the 107 feet below sea level , we have 245 + 107 = 352

so the submarine now is located 352 feet under the sea level
