14 is correct, you could do it a simpler way by dividing 15 by 2 hours to get the unit rate.

sorry but i dunno the answer to number two ill come back if I can figure it out though :)
these are rate questions. 14 can be 7.5mph so it is correct. 15.
[tex]4 \div 3 =1.3 \: so \: 1.3 \times 2 = 2.6[/tex]
so that means she was going 2.6mph on day 1 and for day 2, I don't really know
