The Calef family likes to paddle along the Susquehanna River.
xxTIMURxx [149]

<u><em>Answers:</em></u>

a. \frac{14}{3}=4.667 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 = \frac{14}{3}=4.667 miles/day

<u>Part b:</u>

<u>Now, we are given that:</u>

<u>i. They went half their daily distance:</u>

Daily distance = \frac{1}{2}*\frac{14}{3}=\frac{7}{3} 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 = \frac{7}{3}*6=14 miles

Hope this helps :)
