<h3>Time units.</h3>

1 day = 24h

1h = 60min

We have 4h 20min

$4h + 20min = 4h+\dfrac{20}{60}h=4h+\dfrac{1}{3}h=4\dfrac{1}{3}h=\dfrac{13}{3}h$

$\dfrac{\frac{13}{3}}{24}=\dfrac{13}{3}\cdot\dfrac{1}{24}\\\\\huge\boxed{(D)\ \dfrac{13}{72}}$

6:51PM + 9min → 7:00PM

7:00PM + 27min → 7:27PM

9min + 27min = 36min

$36min=\dfrac{36}{60}h=\dfrac{3}{5}h$

$\huge\boxed{(C)\ \dfrac{3}{5}}$
