Question 894213
 it took you 19 minutes and 37 seconds to run 5 kilometer.
 how long did it take you to run each mile?
:
Change 19 min 37 sec to seconds: 19(60) + 37 = 1177 seconds
Change 5 km to miles: .6214 * 5 = 3.107 miles
:
let t = time to run a mile
Write a ratio equation
{{{t/1177}}} = {{{1/3.107}}}
3.107t = 1177
t = 1177/3.107
t ~ 378.8 seconds which is 6 min 19 sec to run a mile
