Answer:

The speed of the runner is 6 miles per hour.

Step-by-step explanation:

Given the distance between the cyclist and the runner is 68 miles.

Given the speed of the cyclist is 28 miles per hour.

Initial time is 1:00PM Final time is 3:00PM

Time elapsed is 3-1=2hours

Let the cyclist travel a distance of x miles,Then the distance travelled by the runner is 68-x miles.

speed=\frac{distance}{time}

for the cyclist

28=\frac{x}{2}

x=56 miles

the distance travelled by the runner is 68-56=12 miles

speed of the runner =  12/2 = 6 miles per hour

Step2247 [10]

Answer:

8π

Step-by-step explanation:

If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.

The circumference of a circle is 2πr²

Just plug in the variables and you get 2π(2)² which is 8π

4th set = 64 x 4 = 256 letters

5th set = 256 x 4 = 1,024 letters

6th set =1024 x 4 = 4,096 letters

7th set = 4096 x 4 = 16,384 letters

8th set = 16,384 x 4 = 65,536 letters

Each letter cost 2

Total cost = 65,536 x 2 = 131,072
