Two cyclist start from the same point at the same time and move in opposite directions. One cyclist is traveling at 12 mph and the other cyclist is traveling at 14 mph. After 30 minutes are far apart are the two cyclist? Answer in miles.
Thank you!!

t*r=d
t*r+t*r=d
t*(r+r)=d
.5*(14+12)=d
.5*(26)=13 miles apart
