If you would walk around the earths Equator with an average speed of 5 miles per hour, how many days would you need to walk to c
ome back to your starting point?
2 answers:
Well earth's circumference is 24,860 miles
if you walked 24,860 miles at 5 miles per hour it would take you 4,972 hours
4,972 divided by 24 = 207.17
it would take you 207.17 days
The earth equator has circumference of 24901.55 miles !!
so time = distance/ time
= 24901.55 / 5
= 4980.31 hours
so in days, ( divide by 24 ) ,
so, 4980.31/24
=207.5 days !!
so it will take 207.5 days to walk around equator !!
