Math CentralQuandaries & Queries


Question from Bianca, a student:

x represents the number of hours since 8am. y represents the number of children the school nurse has seen during the school day. The nurse has seen 3 children by 8am and 27 children by noon.
How many children has the nurse seen at 2pm?
If the nurse has seen 18 children, what time is it?

Hi Bianca,

There are 4 hours from 8:00 am until noon and the nurse has seen 27 - 3 = 24 children in this time period. If they come at a steady rate how many children has she seen per hour?
