If ms smith class read for 450hrs this month. Ms Brown class read two-thirds the number of hrs read by ms smith class. Ms James class read twice the hrs read by ms brown class. There are 90 students in these 3 classrooms. What was the average number of hrs read by each student?

Ms. Smith >> 450
Ms. Brown >> 2/3 * 450 = 300
Ms. James >> 2 * 300 = 600

Total pages = 1,350

1,350 / 90 = 15 average pages per student
