Question: Tanya was reading a novel, which had 10 chapters. She spent 1 hour(s) reading the first chapter and took the same amount of time to read all the other chapters of the novel. She completed reading the novel in 19 hours. Solve the equation 1 + 9h = 19, to find h, the number of hours she spent reading each chapter other than the first one.
A ) 3 B ) 5 C ) 2 D ) 4
Steps to derive
[Original equation.] 1 1 + 9h = 19
[Subtract 1 from each side.] 2 1 + 9h - 1 = 19 - 1
[Simplify.] 3 9h = 18
[Divide each side by 9.] 49h9 = 189
[Simplify.] 5h = 2
6 Tanya spent 2 hours reading each chapter of the novel other than the first one.
