Question 274139: I have tried this problem over and over and can not come up with the answer. If you could explain steps or how i need to go about tackling this equestion, thanks.
During a road trip, Tony drove one-third the distance that Lana drove. Mark drives 12
more miles than Lana drove. The total distance they drove on the trip was 334 miles. How
many miles did each person drive?
Answer by TheGagePrice(3) About Me  (Show Source):
You can put this solution on YOUR website!
Let d= the distance Lana drove
Let 1/3d= Distance Tony drove
Let d+12= distance Mark drove.
Add all the distances together
D+1/3d+d+12=334
Now add like terms and gett all the "d's" together.
7/3d+12=334
No you must get rid of the fraction so multiply everything by 3.
7D+36=1002
7D=966
D=138
Lana drove 138 miles.
Tony drove 46 miles.
Mark drove 150 miles.
Check your work.
138+46+150=334 miles altogether
Hope I helped >.<
