Question

the deepest point of the Kermandec trench in the Pacific Ocean is 10047 meters below sea level. a s submarine made to dives from above the deepest point of the trench at a rate of 400 meters per minute the first of the two dives was 12 minutes long and the second was five minutes. how far did minutes long and the second was five minutes the submarine t submarine travel in each dive?

Answer 1

Your phrasing is mixed up in the last sentence...

However;

 

Dive 1:

If we dive for 12 minutes at 400 m/minute

we would reach a depth of 12*400 = 4800 meters deep

 

Dive 2:

If we dove for 5 minutes at 400 m/minute we

reach a depth of 5*400 = 2000 meters

 

If the 2nd dive was made from the depth of 4800 m

after the end of the first dive, the final depth would be

4800 + 2000 = 6800 meters deep
