David and his two brothers deliver papers every morning. each one of them can deliver a paper every two minutes, and between the three of them they deliver 147 paper. how many long does is take to deliver the paper.

To deliver 147 papers among the three of them, which each of them delivers a paper every 2 minutes. so every 2 minutes 3 papers are delivered ok so you will need to divide 147 by the number of papers deliver in 2 minutes so that would give us the equation 147/3 and times it by the number of minutes it takes for each person to deliver 1 paper which is 2 so 147/3=49*2=98 so it takes 98 minutes for all three of them to deliver 147 papers
