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

`(9)/(2) = (1)/(3) hour`

`x = (3)/(3)`

`x = ( (9)/(2) * (3)/(3) )/( (1)/(3) )`

`(27)/(6) * (3)/(1) = (27)/(2) = 13 (1)/(2)`
