A washer machine is filling up with water at a constant rate 3/4 of a gallon and 1/5 of a minute. Don calculated the unit rate to be 3/20 of a gallon per minute what did he do wrong

The unit rate would be

(3/4 gal) / (1/5 min)

because the machine is filled with 3/4 gal of water in 1/5 of a minute. Do the arithmetic to get the unit rate of

(3/4 gal) / (1/5 min) = (3/4 • 5) gal/min = 15/4 gal/min

Don's mistake was to multiply 3/4 by 1/5 to get 3/(4•5) = 3/20, but he should have divided by 1/5 instead.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

can you complete your sentence? i could !
