Example Question #425 : Arithmetic
Michael Phelps’ workout program consists of Aerobics, Bench Presses, and Cycling. Aerobics and Bench Presses take a total of 24 minutes, Bench Press and Cycling take a total of 40 minutes, and the entire workout takes a total of 56 minutes. How many minutes are required for the Bench Press portion of his workout?
To find your answer, we would use substitution within a system of equations. If (A+B) +C = 56, we can replace (A+B )= 24 to get (24) + C = 56, Thus making C = 32. Then we can replace C with 32 in the equation B+C = 40, thus making B + (32) = 40 to get an answer of 8.
