540/4 = 132.5 hours
20/4 = 5 hours
Thirty - if I could keep up the pace.
11/3 = [3 and 2/3] miles per hour.
It depends on how fast you can walk, and how many hours you can do without a rest, how long you rest.
The average person could run 9 to 12 miles in three hours. Most people could not run for three hours, so many would walk portions of this challenge.
20/4 = 5 hours
Average walking speed is 4mph so around 17.5 hrs. but you may have to stop for food & drink,
it depends on your average speed and the type of ground you are walking over. For example on a flat even surface you may achieve about 4mph, in which case 90 miles will take just over 22 hours.
If you mean how long does it talk to walk 10 miles then it depends how fast you walk. Taking 2.5mph as quite leisurely and 5mph as very brisk then walking 10 miles will take 2 to 4 hours. 5mph is very brisk even on road, 3 to 4mph is good pace for off road and/or hilly terrain.
Assuming your average walking speed to be 3 miles per hour in 8 hours you could walk 24 miles
time = distance/speeed time = 12.5/2.5 = 5 hours
Alexis because she can walk 5 miles in 4 hours hence in an hour she can walk for 1.25 miles but for Benny, she can walk for 1.33 miles only in an hour.
A brisk walk is about 4MPH, it would take 3hrs 18minutes at that pace.
It will take you two hours to walk six miles.
At 3.1 miles per hour it would take about 21 hours to walk 105km (non-stop).
If you mean how long does it talk to walk 10 miles then it depends how fast you walk. Taking 2.5mph as quite leisurely and 5mph as very brisk then walking 10 miles will take 2 to 4 hours. 5mph is very brisk even on road, 3 to 4mph is good pace for off road and/or hilly terrain.
