Signed is positive number, and direction is downward

Answer:

-5.6 ft

Step-by-step explanation:

Since we are measuring depths this is regularly represented with negative numbers. If the biologist is performing the tests at a point of 33.6 ft depth (-33.6 ft) the first measurement will occur at -33.6/6= -5.6 ft

The following measurements will occur at -11.2, -16.8 ft, -22.4 ft, -28 ft and -33.6 ft
