○ a 0.56 m/s
○ b 0.8 m/s
○ c 1.3 m/s
○ d 1.8 m/s

Explanation:

Step1: Recall speed formula

The formula for speed is $v=\frac{d}{t}$, where $d$ is distance and $t$ is time.

Step2: Substitute values

Given $d = 39$ meters and $t=22$ seconds, so $v=\frac{39}{22}\approx1.77$ m/s. Rounding to one - decimal place gives approximately 1.8 m/s.

Answer:

d. 1.8 m/s
