Question

A fathom is a unit of length, usually reserved for measuring the depth of water. A fathom is approximately 6 ft in length. Take the distance from Earth to the Moon to be 224,000 miles, and use the given approximation to find the distance in fathoms. (Enter a number with the correct number of significant figures.) PLEASE make sure it has the correct number of significant figures. Thank you!!!

Answer 1

Given 1 fathom = 6ft

The significant digit in this conversion is one because 1 fathom is approximately equal to 6ft and not exactly equal.

1mile = 5280ft

In multiplication and division, the resulting quantity will retain as many significant figures as are there in the original number with the least significant figures. In our case the denominator has only one significant figure, so the result will retain only one significant figure.

Therefore,
