Alyssa is jogging near Central Park. She runs along 65th Street for about 0.19 miles, turns right and runs along Central Park West for about 0.28 miles. She then turns right again and runs along Broadway until she reaches her starting point. How long is her total run to the nearest hundredth of a mile?

She runs the first 10 miles at 8 mph" so she spent 10/8 = 5/4 = 1.25 hours so far running.
She has 2 - 1.25 = 0.75 hours leftover.
She has 10 more miles left to run.
-------------------------------------------------------
Distance = Rate * Time
D = r*t
10 = r*0.75
10/0.75 = r
13.3333 = r
r = 13.3333
She has to run approximately 13.3333 mph (on average) to achieve her goal.
