Question 181628
YES!!!!! YOU ARE RIGHT ON!!! GOOD WORK!!!

Distance(d) equals Rate(r) times Time(t) or d=rt;  r=d/t and t=d/t
Let t=amount of time that she rode
Then t+3=amount of time that she ran
Now we are told that:
Time spent riding + time spent running=15 min, so:
t+t+3=15 subtract 3 from each side
t+t=12
2t=12
t=6 min
 

Hope this helps---ptaylor
