A fathom is a unit of length, usually reserved for measuring the depth of water. A fathom is exactly 6.00 ft in length. Take the distance from Earth to the Moon to be 246,000 miles, and use the given approximation to find the distance in fathoms. 1 mile = 5280 ft. Note, this one needs to be in fathoms so make sure you include "fathoms" in the units
