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
Accepted Solution
A:
t = time to hike up the hill3-t is the time to hike down the hill so 4t = 6(3-t)4t = 18-6t10t = 18t = 18/10 = 1.8 hours to hike up the hill1.8 hours = 1 hour 48 minutes
