distance(d)=velocity(v)*time(t)
t = d/v = 1.5*10^11/3*10^8 = 500 seconds or 8.33 minutes

d = v * t
t = d / v = 1.5*10^11 / (3*10^8) = 0.5 * 10^3 = 500 Seconds
or 8 mins 20 seconds

Divide 1.5E11 by 3.0E8, to get the answer in seconds.
Then divide the number in seconds by 60, to get minutes.

take the distance, divide by speed, and you have the time in seconds. divide by 60 to get minutes.
