Tourist 14291

If a tourist reduced his speed by 1 km/h, he would walk less than 12 km in 3 hours. If he added to the step by 1km/h, he would walk more than 25 km in 5 hours. How fast is the tourist?

Correct answer:

x = km/h 4.5

Step-by-step explanation:

3(v1)<12 5(v+1)>25  3v  3 < 12 5v + 5 > 25  3v < 15 5v > 20  5v > 20 3v < 15  v > 4 v < 5  4<v<5  x=4.5
