Answer:
It will take 7 hours for car B to catch up to Car A.
Step-by-step explanation:
So if you write the the two equations out:
You'll want to assume that x is how many hours and y is how many km.
The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.
If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.
Hello, I will try my best to explain this to you as simple as possible.
First, you have to pass the -4 to the other side, like this:
-3 1/2x - 4 = -38 1/8
↓
-3 1/2x = -38 1/8 - 4
Then, you have to subtract -4 from -38 1/8, like so:
-3 1/2x = -38 1/8 - 4
↓
-3 1/2x = -42 1/8
My preferred method for this next step is this:
-3 1/2x = -42 1/8
↓
-7/2x = 337/8
Then, we divide:
-7/2x = -42 1/8
↓
x = (-337/8) / (-7/2)
x = 12.0357142857
So, the answer is: 12.0357142857.
