Question

Nina is training for a marathon. She can run 4 1/2​ kilometers in 1/3​ of an hour. At this pace, how many kilometers can Nina run in 1 hour?
13 1/ 2​ kilometers


14 1/3​ kilometers


4 5/6​ kilometers


12 1/2​ kilometers

Answer 1

Answer:

$\frac{9}{2} = \frac{1}{3} hour$

$x = \frac{3}{3}$

$x = \frac{ \frac{9}{2} \times \frac{3}{3} }{ \frac{1}{3} }$

$\frac{27}{6} \times \frac{3}{1} = \frac{27}{2} = 13 \frac{1}{2}$
