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
