Answer:
Melanie can run faster
Step-by-step explanation:
We can say who runs faster by calculating their speed
Speed = Distance/ Time
Speed of Cara = 3 / (27 1/2) = 3/27.5 = 0.1090 Miles per minute
Speed of Melanie = 6/(53 1/3) = 6/53.3333 = 0.1125 Miles per minute
As we can see the speed of Melanie is higher than that of Cara. Therefore, Melanie runs faster
Answer:
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 = [tex]27\frac{1}{2} =\frac{27*2+1}{2} =\frac{55}{2} minutes[/tex]
Speed of Cara = Distance / Time = [tex]\frac{3}{\frac{55}{2} } =\frac{6}{55}=0.109miles/min[/tex]
Melanie can run 6 miles in 53 1/3 minutes
Distance traveled = 6 miles
Time taken to travel 6 miles = [tex]53\frac{1}{3} =\frac{53*3+1}{3} =\frac{160}{3} minutes[/tex]
Speed of Melanie = Distance / Time = [tex]\frac{6}{\frac{160}{3} } =\frac{18}{160}=0.1125miles/min[/tex]
Speed of Melanie > Speed of Cara.
Melanie is running faster.
