Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).
If you do

, your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
To find the area of a triangle, use the formula that is A= 1/2(base x height)
2x 10 = 4x - 1
-2x - 10 = -1
-2x = 9
x = -9/2
y = 2(-9/2) -10
y = -9 - 10
y= -19
