Answer:
[tex]\dfrac{17}{30}[/tex] minutes.
Step-by-step explanation:
It is given that Sally takes [tex]2\dfrac{5}{6}[/tex] minutes to drive from her home to the local shopping center.
[tex]2\dfrac{5}{6}=\dfrac{2(6)+5}{6}[/tex]
[tex]2\dfrac{5}{6}=\dfrac{12+5}{6}[/tex]
[tex]2\dfrac{5}{6}=\dfrac{17}{6}[/tex]
She spends 1/5 of this time waiting at traffic lights.
Waiting time in traffic [tex]=\dfrac{17}{6}\times \dfrac{1}{5}[/tex]
[tex]=\dfrac{17}{30}[/tex]
Therefore, waiting time is [tex]\dfrac{17}{30}[/tex] minutes.
