I got a bit more than $8 \text{min}$

#### Explanation:

Light in vacuum travels at a speed $c = 3 \times {10}^{8} \frac{m}{s}$.
A beam of light must travel:
$\frac{93 \times {10}^{6}}{0.62} = 1.5 \times {10}^{8} k m = 1.5 \times {10}^{11} m$

We can find the time remembering that:

$\text{speed"="distance"/"time}$

So:
$\text{time} = \frac{1.5 \times {10}^{11}}{3 \times {10}^{8}} = 500 s$

corresponding to:

$8 \text{min}$ and $20 s$
