Since the woman is jogging at 6 mi/h, in 10 minutes she will have jogged:
[tex]\frac{10}{60}\cdot6=\frac{60}{60}=1mi[/tex]in a similar way, we can find the distance that the man traveled in 10 minutes, considering his speed of 12 mi/h:
[tex]\frac{10}{60}\cdot12=\frac{120}{60}=2mi[/tex]since the woman traveled 1 mile and the man traveled 2 miles, we have that after 10 minutes, they are 1+2= 3 miles apart
