P=2(L+W)
L=2/3x+10
W=1/3x+5
P=2(2/3x+10+1/3x+5)
P=2(2/3x+1/3x+10+5)
P=2(3/3x+15)
P=2(x+15)
P=2x+30

Using the given information, the unit rate is 0.0645 miles/minute
<h3>Calculating rate </h3>
From the question, we are to determine the unit rate
From the given information,
Daniel runs 40/5 miles in 124 minutes
That is,
Distance = 40/5 miles = 8 miles
Time = 124 minutes
Using the formula,
Rate = Distance / Time
Rate = 8 miles / 124 minutes
Rate = 0.0645 miles/minute
Hence, the unit rate is 0.0645 miles/minute
