Solving a Word Problem Involving the Average Rate of Change

WebThe equation to solve is: 1 R + 1 2R = 1 10 h, where Doug's rate ( 1 D) = 1 2 × Becky's ( 1 R) rate. Sum the rates: 1 R + 1 2R = 2 2R + 1 2R = 3 2R Solve for R: 3 2R = 1 10 h which means 1 R = 1 10 × 2 3 h so 1 R = 2 30 or R = 30 2 1 R + 1 2 R = 1 10 h, where Doug's rate ( 1 D) = 1 2 × Becky's ( 1 R) rate. WebThe unknown in this problem is the rate or percentage. Since the statement is " (thirty) is (some percentage) of (twenty)", then the variable stands for the percentage, and the equation is: 30 = ( x ) (20) 30 ÷ 20 = x = 1.5. Since x stands for a percentage, I need to remember to convert this decimal back into a percentage: 1.5 = 150%. church and larson
