Problema Solution
Suppose you take a hike up a hill at a rate of 4 mi/h. You hike back down the hill at 6 mi/h. The total time you spent on the hiking trip was 3 hours. How much time did it take you to hike up the hill?
Answer provided by our tutors
hike upe rate = 4 mi/h and hike down rate = 6 mi/h
total time is 3 hrs
4t = 6(3 - t)
== > 10t = 18

hence, it requires 1.8 hrs to hike up the hill
