-21b +49; b = 42 => 2*
-21*42 + 49 =
3528 - 882 + 49 = 2695;
3528 - 882 + 49 = 2695;

So, initially 240
-212 
were empty:
this is :
12/4 is 4 so that's why i substituted it with 4.
now, later 27 1/3 were used so we add this tho the original empty space
= 
= 
which is the result!

Answer:
Step-by-step explanation:
Given: A tourist first walked 17km with a speed of v km/h.
Since
therefore,
Let be the time he walked with speed v.
then
Also he hiked 12 km uphill with the speed that was 2 km/hour less than his original speed.
Let be the time he hiked 12 km,
Then
The total time for the whole trip is given by:-
Substitute the values of and
in the equation, we get
