You can find the answer on wikipedia, or you can calculate it and get approximately the same answer you'd find there.
t = d/v (Time = distance / velocity)
t = 15 x 10^10 m / 3 x 10^8 m/s
t = 500 s
Now use dimensional analysis to find out how many minutes 500 s ends up being.
500 s x (1 min / 60 s) = Time
500 s*min / 60 s = time
units cancel out like variables
500 min / 60 = time
time = 8.33 min or about 8 min 20 seconds

It's about 8 minutes. More specifically, divide 1.5E11 meters by 3E8 meters per second to get 500 seconds.
