A jogger runs at a speed of 4 m/s for 500]s, slows to 2.5 m/s for the next 300 s and then travels the final 900 s at a speed of 3.5 m/s. What is the
average speed of the jogger in m/s?
O 10 m/s
O 3.47 m/s
O 5 m/s
O 3.33 m/s

3.33 m/s

Explanation:

Just add up all of the speeds and divide it by 3 (since there are 3 different speeds)

(4 m/s + 2.5 m/s + 3.5 m/s) / 3 = 3.33 m/s

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
