Question 668321: Hello! Please help me solve these problems.
1) A family takes a 246 mile road trip and it takes the 6 hours to reach their destination. What is their average rate for the trip?
(A)1476 miles per hour
(B)82.0 miles per hour
(C)0.02 miles per hour
(D)41.0 miles per hour
The problem with this problem is if I multiply 246*6=1476 mph, but if I divide 246/6=41.0 mph. I just feel like something is wrong. Please explain to me.

2)The value of a house decreased from $216,000 to $164,000. Determined the percent decrease for the value of the house.
3) Select the expression that is equivalent to -2(x-3).
(a) -2x-6
(b) -2x+3
(c) -2x+6
(d) -2x-3
4) Solve the inequality. 0.3(0.3x+0.8)_< -0.3
This triangle here has a line under it. Sorry I just couldn't find a way to fix that to be together.
(a) x_>-6
(b) x<_6
(c) x_>6
(d) x<_-6

1) A family takes a 246 mile road trip and it takes the 6 hours to reach their destination. What is their average rate for the trip?
(A)1476 miles per hour
(B)82.0 miles per hour
(C)0.02 miles per hour
(D)41.0 miles per hour
Speed = distance / time
distance = 246
time = 6 hours
246/6
=41 mi/h
2)The value of a house decreased from $216,000 to $164,000. Determined the percent decrease for the value of the house.
%28%28216000-164000%29%2F216000%29%2A100
52000%2F216000%29%2A100
24%
3) Select the expression that is equivalent to -2(x-3).
(a) -2x-6
(b) -2x+3
(c) -2x+6( correct)
(d) -2x-3
4) Solve the inequality. 0.3(0.3x+0.8)_< -0.3
0.09x%2B0.24+%3C=0.3
0.09x%3C=0.3-0.24
0.09x%3C=0.06
x%3C=0.66
