tony and his friends are on the beautify our community committee. tony can collect 3 bags of trash per hour. ralph can collect 1 bag per hour and Della can collect two bags per hour. after how many hours does tony collect as much trash as ralph and Della combined
This question is not difficult
tony=3 bags/hour
R and D =(1+2)=3 bags /hour
After 1 hour R and D have collected the same as Tony
