Explanation:

Step1: Count number of dots per value

There are 2 dots at $\frac{1}{2}$, 5 dots at 1, 1 dot at $1\frac{1}{2}$, 2 dots at 2, 2 dots at $2\frac{1}{2}$.

Step2: Calculate total time

Multiply each value by the number of dots and sum. [ \begin{align*} &2\times\frac{1}{2}+5\times1 + 1\times1\frac{1}{2}+2\times2+2\times2\frac{1}{2}\ =&1 + 5+\frac{3}{2}+4 + 5\ =&1 + 5+1.5+4 + 5\ =&16.5 \end{align*} ]

Answer:

$16.5$
