Question 794577
Let's say I'm walking 2 minutes and 30 seconds every 130 meters, how long would it take for me to walk 5 km? and how long would it take if I were to walk a marathon of 26.2 miles. 
:
Find your speed in meter/min (speed = dist/time)
Change 2 min 30 sec to 2.5 min
s = {{{130/2.5}}}
s = 52 m/min is your speed
:
"how long would it take for me to walk 5 km?" 
Time = dist/speed
Change 5 km to 5000 meters
t = {{{5000/52}}}
t = 96.154 min which is 96 + .154(60) = 96 min 9.23 sec
:
"how long would it take if I were to walk a marathon of 26.2 miles."
Change miles to km
1.609*26.2 = 42.156 km
Change to meters
1000 * 42.156 = 42156 meters
Find the time to cover this distance
t = {{{42156/52}}} = 810.7 minutes
that's 13 hrs 30 min 42 seconds
