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.

-4.4(s - 2) + 6.9s = 14.8

Distribute -4.4 into the parenthesis:

-4.4s + 8.8 + 6.9s = 14.8

Combine like terms:
2.5s + 8.8 = 14.8

Subtract 8.8 from both sides of the equation:

2.5s + 8.8 - 8.8 = 14.8 - 8.8

2.5s = 6

Divide both sides by 2.5:

2.5s/2.5 = 6/2,5

s = 2.4

s =
