There are 5280 feet in a mile. Knowing this, we can make the conversion from 2640 feet per hours to miles per hour:
(2640/5280)/1 hour = 0.5 miles / hour

Using statistical concepts, it is found that:
- The mean practice time decreases because of the outlier.
- The median practice time does not change because of the outlier.
- The range increases because of the oulier.
<h3>What are the mean, the median and the range of a data-set?</h3>
- The mean is the sum of all observations divided by the number of observations.
- The median is the middle value, the value that separates the upper 50% from the bottom 50%.
- The range is the difference between the largest value and the smallest.
From their concepts above, we have that the mean and the range are influenced by outliers.
In this problem, the outlier is at the low end, of 15, hence:
- The mean practice time decreases because of the outlier.
- The median practice time does not change because of the outlier.
- The range increases because of the oulier.

Answer:
Letters as in the attached image.
Triangles ABC and ADC are congruent by SSS. From that, corresponding angles are congruent, in parcicualre B and D, both measuring 94°.
Final angle is obtained by difference. The internal angles of a quadrilater add to 360, so the remaining is 360-90-94-94 =82°
