My friend sets out walking at a speed of $3$ miles per hour. i set out behind her $5$ minutes later at $4$ miles per hour. for how many minutes will my friend have been walking when i catch up to her?

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
