The number of minutes Samantha needs to run on Friday to reach her goal is 45 minutes.
<h3>Average</h3>
- Monday = 45 minutes
- Tuesday = 30 minutes
- Wednesday = 55 minutes
- Thursday = 25 minutes
- Friday = x minutes
Average = (Monday + Tuesday + Wednesday + Thursday + Friday) / 5
40 = (45 + 30 + 55 + 25 + x) / 5
40 × 5 = 155 + x
200 = 155 + x
200 - 155 = x
45 = x
x = 45 minutes
