Answer:

3.4 lessons per week

Step-by-step explanation:

So to find the number of lessons for 6 chapters we need to multiply 8.5 by 6:

8.5 × 6 = x

x = 51 - so we need 51 lessons to finish six chapters

To find the number of lessons per week, we need to divide the number of lessons by the number of weeks:

y = 51 ÷ 15

y = 3.4

So the teacher needs 3.4 lessons per week to teach 6 chapters in 15 weeks.
