Problema Solution
Tina hiked 15km up a mountain trail. Her return trip along the same trail took 1/2 hour less, because she increased her speed by 1km/hr. How long did it take her to climb up and don the trail?
Answer provided by our tutors
If you hike 5km/h, it would take 3 hours to hike up the mountain
If you increase to 6km/h on the way down, it would take 2 hours, 30 minutes.
Therefore, it took 5 hours 30 minutes to climb up and back down.
