In the given question, we have to find the weight of 93 pound person on moon.
We will use unitary method to solve this problem.
"The unitary method is a technique which is used for solving a problem by finding the value of a single unit, i.e., 1, (by dividing) and then finding the necessary value by multiplying the single unit value".
Weight of person on moon with 120 pounds on earth = 20 pounds on moon
Weight of person on moon with 1 pound on earth = [tex] \frac{20}{120} [/tex] pound on moon
Weight of person on moon with 1 pound on earth = [tex] \frac{1}{6} [/tex] pound on moon
Now, Weight of person on moon with 93 pounds on earth = [tex] \frac{1}{6} \times 93 [/tex]
= [tex] \frac{93}{6} [/tex]
= 15.5 pounds.
So, a 93 pound person on earth weighs 15.5 pounds on moon.
