Answer:
Accelerating to top speed, deaccelerating to finish line.
Step-by-step explanation:
If the runner kept a constant speed of 11 mph for the whole duration of his run (32 minutes), the distance he would have covered is:
This means that, in order to run the full 6.2 miles, the runner needs to reach a speed over 11 mph. Assume he starts from rest, while accelerating the runner reaches, and the surpasses, the 11 mph mark. Since his speed at the finish line is zero, the runner has to deaccelerate from his current running speed (which should be higher than 11 mph), passing through 11 mph and reaching zero at the finish line.

Answer:
( x + 9)² + y² = 20
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r², where the center is (h, k) and r is the radius. By plugging in the given numbers from the question, we have [ x – (-9)]² + ( y - 0)² = (2√5)².
( x + 9)² + y² = (2)(√5)(2)(√5)
(2)(2) = 4 (√5)(√5) = 5 (4)(5) = 20
( x + 9)² + y² = 20
" the difference " means subtract
the difference between 5 and twice a number x is 1
5 - 2x = 1 <== ur equation
-2x = 1 - 5
-2x = - 4
x = -4/-2
x = 2 <== ur solution
That would be 250%
1 whole plus 1 whole would be 200
1 half would be 50
