Missing info attached below

Depth_of_the_frequency_signal = -180 4/7  ft =  -1264/7 ft

Depth_of_the_submarine  = -116 2/7  ft =  -814/7 ft

Net_change_in_depth =

Depth_of_the_submarine  -  Depth_of_the_frequency_signal

Net_change_in_depth  =  -814/7 ft  -  (-1264/7 ft)

Net_change_in_depth  = 450/7 ft = 64 2/7 ft
