Melanie is running faster.

Explanation:

Cara can run 3 miles in 27 1/2 minutes .

Distance traveled = 3 miles

Time taken to travel 3 miles = $27\frac{1}{2} =\frac{27*2+1}{2} =\frac{55}{2} minutes$

Speed of Cara = Distance / Time = $\frac{3}{\frac{55}{2} } =\frac{6}{55}=0.109miles/min$

Melanie can run 6 miles in 53 1/3 minutes

Distance traveled = 6 miles

Time taken to travel 6 miles = $53\frac{1}{3} =\frac{53*3+1}{3} =\frac{160}{3} minutes$

Speed of Melanie = Distance / Time = $\frac{6}{\frac{160}{3} } =\frac{18}{160}=0.1125miles/min$

Speed of Melanie > Speed of Cara.

Melanie is running faster.
