###Human: Bess and Holly are playing Frisbee at the park. Bess can throw the Frisbee as far as 20 meters and she does this 4 times. Holly can only throw the Frisbee as far as 8 meters and she does this 5 times. Each time Bess throws a Frisbee, she throws it back to her original position. Holly leaves her Frisbee where it lands every time she throws it. In total, how many meters have the thrown Frisbees traveled?, ### Assistant: Bess throws the Frisbee out 4 times * 20 meters each time = 80 meters.
She then throws it back which doubles the distance traveled to 80 meters * 2 = 160 meters.
Holly throws the Frisbee out 5 times * 8 meters = 40 meters.
So in total, Holly and Bess have thrown the Frisbees 160 + 40 = 200 meters. 
 So the answer is :  200
