Astudent solved this problem and said the answer was hour. cindy rode her bike for hour and ran for hour. what was the total length of time that cindy exercised? is the student's answer reasonable?
a. yes, the answer is reasonable.
b. no, the answer is not reasonable. it should be about 2 hours.
c. no, the answer is not reasonable. it should be about hour.
d. no, the answer is not reasonable. it should be about 6 hours. swer reasonable?

The answer would be a. Yes, the student’s answer is reasonable.

In the problem, it states that Cindy rode her bike for an hour and ran for an hour.  Without the presence of the comma between rode her bike for an hour, and ran for an hour, this just means that Cindy only rode her bike and ran it for an hour.

The sentence can be written as Cindy rode her bike and ran for an hour.  So, this gives an answer that Cindy only exercise for an hour.

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.
