The first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour
Yea its is reasonable. Hope i helped :)

The expression for the area of the shaded region is s^2 - pir^2
<h3>Area of composite figure</h3>
The formula for calculating the area of the shaded part in the given equation is expressed as:
Area area of square. - area of circle
Since
Area of square = s^2
Area of circle = pir^2
substitute
Area of shaded part = s^2 - pir^2
Hence the expression for the area of the shaded region is s^2 - pir^2
