Answer:
0.8
Step-by-step explanation:
To find the answer to this question multiply the rate by the time he runs.
The rate tells us how many miles he runs during certain time. Once given a time, 12 minutes,
we have to multiply the rate which must be expressed as a quotient (3miles/45minutes) times the given time:
[tex]12Min ~x~\frac{3~miles}{45~Min} =0.8[/tex]
It means that he runs 0.8 miles in 12 minutes.
