Answer:
x 19/6
Step-by-step explanation:
1. Multiply both sides by 6 (the LCM of 6,3)
5/2 + 3-x <= 2(x-2)
2. Simplify 5/2+3-x to 11/2-x
11/2 - x<=2 (x-2)
3. Expand.
11/2-x<= 2x-4
4. Add x to both sides.
11/2<= 2x-4+x
5. Simplify 2x-4+x to 3x-4.
11/2<=3x-4
6. Add 4 to both sides.
11/2+4<=3x
7. Simplify 11/2+4 to 19/2
19/2<=3x
8. Divide both sides by 3
19/2 /3 <=x
9. Simplify 19/2 /3 to 19/2*3
19/2*3<=x
10. Simplify 2*3 to 6
19/6<=x
11. Switch sides.
x>= 19/6

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
