Explain why if a runner completes a 6.2â-mi race in 32 âmin, then he must have been running at exactly 11 âmi/hr at least twice

MA_775_DIABLO [31]

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:

$d=11*\frac{32}{60}\\d= 5.87\ mi$

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.

What is the value of y?

NNADVOKAT [17]

Answer:

y = 40

Step-by-step explanation:

Lets make an equation to represent the sum of the angles:

We know that the sum of angles of triangles equals 180 degrees. So based on this knowledge, the equation is :

2y + y + 10 + 50 = 180

Now we simplify:

2y + y = 3y

10 + 50 = 60

So our new equation is 3y + 60 = 180

Now all we have to do is simplify:

3y + 60 = 180

3y + 60 -60 = 180 - 60

3y = 120

3y / 3 = 120 / 3

y = 40

So the answer is 40 hope this helped
