Use the trip back to calculate total distance. If Brenda drives 30 mph for 6 hours then she has traveled 180 miles. Now we know it is 180 miles from her house to the train station. If she drove this in 5 hours instead, just divide 180 by 5 to get an average speed of 36 mph.

Answer:
x = 8
Step-by-step explanation:
-1/4 (2x + 8) = -6
Multiply both sides by -4.
2x + 8 = 24
Subtract 8 from both sides.
2x = 16
Divide both sides by 2.
x = 8
x + (x+1) + (x+2) = 1200
combine like terms
3x+3=1200
subtract 3 from each side
3x =1197
divide by 3
c =399
Answer: 399, 400, 401
