Answer:
1. At this rate Javier can fold 90 t-shirts in an hour. I know this because, by divided 6 by 4 you are able to find out how many shirts he is able to fold in one minute, which is 1.5. If there are 60 minutes in an hour and Javier can fold 1 1/2 t-shirts every minute, if you multiply the two, you find that rate Javier can fold 90 t-shirts an hour.
2. At this rate the school nurse see's 39 students in a 6-hour day. I know this because, by dividing the total number of students she sees daily (52) by the whole school day (8 hours) you can find out that she gets about 6 or 7 students per hour. If it was a 6-hour day, you would simply multiply 6.5 by 6 to get 39 students within a 6 hour time period.
