Jim reads at a rate of 40 pages an hour. He reads a total of 600 pages per week. He increases his reading speed to 150% of its former speed but reads 4 hours less per week. How many pages does he read a week now?
Thoughts? Step-by-step reasoning:
He read 600 / 40 = 15 hours per week. So now he reads 15 - 4 = 11 hours per week. She now reads 40 * 1.5 = 60 pages per hour. So she reads 11 * 60 = 660 pages per week.
Thus, the answer is 660.
