A bus route has 20 stops at intervals of five minutes. Call the place where the route begins "Stop 0', and call the first stop after this "Stop
1", and so on. The relief bus driver, who is initially stationed at Stop O,
must meet the bus after it has been on route for seven and one
quarter hours. Answer the following questions to determine at which
stop the relief driver should meet the bus.
a. How many five-minute intervals make up seven and one
quarter hours?
(Hint: An hour has 12 five-minute intervals.)

b. How many stops will the bus have made after seven and one
quarter hours?

C Fill in the blanks: After seven and one quarter hours, the
number of the stop where the bus will be is the remainder
that is obtained when ———- is divided by ————-
d. At which stop should the relief bus driver meet the bus?

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem.
