10 minutes ago, the diver was 450 feet deep.
Distance is the total movement of an object without regard to its direction.
Now it is given that,
Distance at which the diver was = 200 feet
Rate at which diver is pulled up = 25 feet per minute
Now in 10 minutes distance covered by diver,
Distance covered in 10 minutes = Rate at which diver is pulled up x 10
⇒Distance covered in 10 minutes = 25x10 feet
⇒Distance covered in 10 minutes = 250 feet
Hence, Position of diver 10 minutes ago = Distance at which the diver was + Distance covered in 10 minutes
⇒Position of diver 10 minutes ago = 200 feet + 250 feet
= 450 feet
Hence,10 minutes ago, the diver was 450 feet deep.
