Find rate first: R = distance / time = 1.1 mile / 10.4 minutes (24 / 60 = .4 minutes)
R = .106 miles per minute
Now, solve for time: t = distance / Rate = 0.8 mile / .106 mile / min
t = 7.56 minutes = 7 minutes 33.6 seconds

7:34
10:24 = 624 seconds
624/1.1 = 567.3
567.3 * 0.8 = 453.82 seconds = 7 minutes 34 seconds
Of course, that's if you kept the exact same pace the whole way. If you got tired and slowed down towards the end (which I would imagine someone who ran a mile in more that 9 minutes would have done), you would be able to run 8/10 of a mile a little faster than that.
probably around 7:15

1.1/10:24=.8/x
