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
-1.5 ------ f(x) = 3(-1.5) - 5
= -4.5 -5
= 9.5
2 -------- f(x) = 3(2) - 5
= 6 -5
= 1
4 -------- f(x) = 3(4) - 5
= 12 - 5
= 7
(9.5, 1 , 7)
Area of a rectangle is
A=L*W=6.3ft * 2.5ft=15.75 ft^2
we know that 1 ft^2=144 in^2
15.75ft^2*144=2268in^2
