Question

The mountain trail at Tanner Park is 8 miles long traveling to the top of the mountain and back. Grayson is making his way back down after hiking 4.6 miles. He needs to hike for another 2 hours to make it to the bottom. How many miles will he hike per hour? 7th-grade question

Answer 1

Speed of hike = 1.7 miles per hour

Explanation:

Given:

Total distance = 8 miles

Distance already traveled = 4.6 miles

Total time remain to travel = 2 hour

Find:

Speed of hike

Computation:

Distance remain = Total distance - Distance already traveled

Distance remain = 8 miles - 4.6 miles

Distance remain = 3.4 miles

Speed of hike = Distance remain / Total time remain to travel

Speed of hike = 3.4 / 2

Speed of hike = 1.7 miles per hour
