Plz help Starting at sea level, a submarine descended at a constant rate to a depth of −34 mile relative to sea level in 5 minutes. What was the submarine's depth relative to sea level after the first minute?

Enter your answer in the box as a fraction in simplest form.

Uneed to add them up 27+18+23=68

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
