Trent hikes up a hill at 4 km/h. he hikes back down at 6 km/h. the hiking trip took 3 hours. how much time did it take trent to hike up the hill? write an equation you can use to solve for t, the time it took him to climb up the hill

t = time to hike up the hill

3-t is the time to hike down the hill

 so 4t = 6(3-t)

4t = 18-6t

10t = 18

t = 18/10 = 1.8 hours to hike up the hill

1.8 hours = 1 hour 48 minutes

step-by-step explanation:
