Answer:

A. 14 meters

B. 24 meters

Step-by-step explanation:

A. Mellisa starts at 29 meters deep, then rises 15 meters.  So her final depth is 29 − 15 = 14 meters.

B. Melissa starts at 40 meters deep, then rises 2 m/min for 8 minutes.  That means she rises a total distance of 2 × 8 = 16 meters.  So her final depth is 40 − 16 = 24 meters.

Answer:

At one point, Mellisa is 29 meters below the surface of the water.

A.

As she swims around for the fish, she swims for 12 mins and rises upward by 15 meters.

So, her final depth at the end of the 12 minutes = 29-15=14 meters

B.

Mellisa is at a depth of 40 meters. Every minute, she rises 2 meters.

So, in 8 minutes she will rise 2\times8=16 meters

Her depth will be = 40-16=24 meters
