45 is the second answer to the second question.i don't know the first question

To find out how many quarter hours Paula and Sam spent in the park, we need to convert the given time, which is in minutes, to quarter hours.

First, let's convert 30 minutes to hours. Since there are 60 minutes in an hour, we can divide 30 minutes by 60 to get the equivalent in hours:

30 minutes ÷ 60 = 0.5 hours

Now, to convert the 0.5 hours to quarter hours, we will divide it by 0.25 (since there are 4 quarter hours in an hour):

0.5 hours ÷ 0.25 = 2 quarter hours

Therefore, Paula and Sam spent 2 quarter hours in the park.
