Answer:
3.5 hours
Step-by-step explanation:
if you multiply 6 and 2 by 3.5, then add them you get 28

So, your answer to this problem is
c = 4.
There's not much you can or should do here other than to "solve for d."
Subtract 22 from both sides. Then 22 - 22 - 28d = -12 - 22 = -34
Then -28d = -34, and d = -28 / (-34) = + 14/17 (answer)
the answer for this question is p=5/3 ,(q)=3/2
