Question

A piano teacher has 4 1/2 hours available to teach in a night. Each lesson will last 1 1/2 hours. How many lessons can the teacher schedule in a night?

Answer 1

3 lessons

Explanation:

available hours: 4 hrs 30 min

time per lesson: 1 hr 30 min

2 lessons is 3 hrs

which leaves even time for one more lesson after 2 lessons

So, she can schedule 3 lessons in 4 hrs in 30 min
