Answer:
1.436 or this=−2.436
Step-by-step explanation:
Solve it by finding out how many times 22 can be put into 22, which is once, so the answer is 1.
I believe the answer to this is correct and i believe he did this by adding(i think)
Begin by finding the two equations like this:
Janelle equation:

.
Swetha equation:

since y = 12 when the time t = 0.
In order to find how many time it takes to Janelle in order to catches
up solve the equation:

Solving the above equation for t we get:
So she catches up after 16 minutes. Compute like this:
They were on question 32 then.
Divide 4 with -0.5 to get
-10 -6 -8(-2)
then multiply -8 and -2 to get
-10-6+16
then add -10 and -6 to get you to
-16+16
=0
