Question 938392
Lets fist convert the length of the trail to meters.
In 8.7km, the k stands for 1000.
{{{8.7*1000 = 8700}}}
The length of the trail in 8700m.
We know that you can hike 1800m in one hour.
Divide the length of the trail by that given speed.
{{{8700 / 1800 = 4.833}}}
It will take 5 hours to complete the hike.
