<u>Answer:</u>
-
It will take 1 week for both classmates to catch up with each other
- Each child has passed about 9 tests.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
-
Q = 8 + 1(w)
- S = 4 + 5(w)
- Q = S
<u>Work:</u>
-
8 + w = 4 + 5w
- => 8 - 4 = -w + 5w
- => 4 = 4w
- => w = 1
<u>Hence, it will take 1 week for both classmates to catch up with each other. Now, let's substitute the value of w into the first equation to find how many tests have each child passed.</u>
-
Q = 8 + (w)
- => Q = 8 + 1
- => Q = 9
Hence, <u>each child has passed about 9 tests.</u>
