3.0 x 10^8 km/s is how far light travels.
3.0 x 10^8 km/s x 60s is how far light travels in a minute
3.0 x 10^8 x 60 x 5 is how far light travels in 5 minutes, and you should get D as your answer.
First, divide -5 on both sides:
(x + 7) < -2
Then subtract 7 on both sides:
x < -9
x < -9 is your final answer.
