One-half hour later, his cousin Darryl started from the aunt's house on a bicycle to meet him, riding 10 miles per hour. How long will Darryl ride before he meets Jerry?

You can put this solution on YOUR website! 3t+10(t-.5)=12
3t+10t-5=12
13t=12+5
13t=17
t=17/13
t=1.3 hours is the time for Jerry.
3*1.3=3.9 miles for Jerry.
12-3.9=8.1 miles is the distance Darryl traveled.
