Answer:

the initial temperature= -12.6⁰c

the final velocity = x

-12.6-7.5=x

-20.1=x

so therefore the final temperature is -20.1

velikii [3]
So here is the solution to the given problem above.
Given that Serena drove 40km on 3L of gasoline, we can say that she drove 13.33 kilometers per liter of gasoline. Since we want to find out how far she travelled with a full tank of 50L, we will only multiply 13.33 by 50 and we get 666.67 kilometers. So the answer would be 666.67 kilometers for 50 L of gasoline. Hope this helps.
