Answer: The runner’s average speed is 3 m/s.

Step-by-step explanation:

Hi, to solve this problem we have to multiply the length of the track (402.2 meters) by the times that joe ran around it (8.25 times).

So, mathematically speaking:

  • 402.3m x 8.25 = 3,318.975 meters

Now that we have this result, we have to divide it by the time ( 1,119.803 sec), to obtain the speed rate.

  • 3,318.975 m/ 1,119.803 sec = 2.97m/sec= 3 m/s

In conclusion, the runner’s average speed is 3 m/s.

Feel free to ask for more if it´s necessary or if you did not understand something.

Likurg_2 [28]

Answer:

8 ft; 6 m; 28pi ft; 10pi mm

Step-by-step explanation:

1. Radius = diameter/2

16/2=8

Therefore, 8 ft

2. Diameter= radius * 2

3*2=6

Therefore, 6 m

3. Circumference = 2*pi*r

2*pi*14=28pi

Therefore, 28pi ft

4. Circumference = pi*d

Therefore, 10pi mm

I hope this helped and have a good rest of your day!

Two persons start running simultaneously from a certain point, one towards south and another towards east. After 2 hours, the di

The Pythagorean theorem is sometimes known as Pythagoras' theorem. The speed of the faster person is 40 kmph.

<h3>What is Pythagoras' theorem?</h3>

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.

Let the speed of one person be represented by x, then the speed of the other person, if the speed of the second person is 75% of the first.

  • Speed of first-person = x
  • Speed of second-person = 75% of Speed of first-person = 0.75x

Now, the distance covered by two persons in 2 hours is,

  • Distance covered by the first-person = x × 2 = 2x
  • Distance covered by the second-person = 0.75x × 2 = 1.5x

Since one person runs towards the south and another towards the east. Therefore, will form a 90° angle between their directions.

Now, the distance between the two after two hours is 100 km, therefore, we can write,

(2x)² + (1.5x)² = 100²

4x² + 2.25x² = 10000

6.25x² = 10000

x² = 10000/6.25

x² = 1600

x = √1600

x = 40

Hence, the speed of the faster person is 40 kmph.
