I run around a circular track, with radius 25m, for 4 and 1/4 times before stopping. It takes me 16
minutes. (A) What is my speed? (B) What is my velocity? (Don't worry about direction)

Respuesta :

Answer:

See below

Explanation:

Distance around track = circumference =  pi * 2 r = pi * 2 * 25

   = 157 m

  4 1/4 times = 667.6 m

speed = 667.6 m / 16 min = 41.7 m/ min

  magnitude of velocity is the same   41.7 m/min

(= .695 m/s)
