Question: Out of the 150 teachers on the school basketball court, 60% are history teachers. If the rest of the teachers on the court are math teachers, and each teacher sleeps for 6 hours a day, calculate the total time the math teachers collectively spend sleeping in one day.
Work out the solution step by step. 
Answer: 
The total number of teachers in the basketball court who teaches history is 60/100*150 = 90
This means there are 150-90 = 60 math teachers are on the basketball court.
If each teacher sleeps for 6 hours daily, the total amount of time the math teachers sleep in a day is 60*6 = 360 hours.
