a. miles/day
b. 14 miles
<u><em>Explanation:</em></u>
<u>Part a:</u>
We are given that they paddled a total distance of 14 miles for 3 days. To get the distance paddled each day, we will divide the total paddled distance by the number of days
<u>This is done as follows:</u>
Distance paddled each day = miles/day
<u>Part b:</u>
<u>Now, we are given that:</u>
<u>i. They went half their daily distance:</u>
Daily distance = miles/day
<u>ii. They extended the trip twice as many days</u>
Number of days = 2 × 3 = 6 days
The total distance paddled will be equivalent to the product of the distance paddled each day and the total number of days
<u>This means that:</u>
Total distance = miles
