Thats simple.
Today's tecnology and a little bit of maths can help us find that out.
The speed of light is the same no matter what is the brightness of it. So, the scientists used a strong, extremely bright light to reach a distance of 5km. Then, they used the following formula:
Speed = Distance/Time

that would take just 0.00016 seconds to travel
how could they measure it
1.6*10^-4 s!!
