Kevin hiked up lambs Canyon and two hours and then ran back down in one hour has been running downhill was 2.8 mph greater than his speed hiking uphill how far of the canyon did he hike

Answer: he hiked 5.6 miles up the canyon.

Step-by-step explanation:

Let x represent his speed hiking uphill.

His speed running downhill was 2.8 mph greater than his speed hiking uphill. This means that his speed running downhill would be x + 2.8

Distance = speed * time

Kevin hiked up Lamb's Canyon in 2 hours. This means that the distance covered by hiking uphill is 2 * x = 2x

He ran back downhill in 1 hour. This means that the distance covered by running downhill is 1 * (x + 2.8) =

x + 2.8

Since the distance uphill is the same as the distance downhill, then

2x = x + 2.8

2x - x = 2.8

x = 2.8

Therefore, the distance hiked up the canyon is

2x = 2 * 2.8 = 5.6 miles
