If a student can run the mile in 8 minutes, how many miles can they run in an hour?

7 1/2 miles

1 mile= 8 min, 2 mile=16 min, 3 mile=24 min, 4 mile=32 min, 5 mile=40 min, 6 mile=48 min, 7 mile=56 min and then 4 min is 1/2 of 8 min for the remainder

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
