Jerod ran from the 2-mi marker to the finish line of a 5-mi race in 25 min.
At this rate, how long would it take Jerod to run a 10-km race?
:
J ran 3 mi in 25 min
Change 3 mi to km; 1.609 * 3 = 4.827 km
:
Write a ratio equation to find the minutes to run a 10 km race
let t = time to do this
t%2F25 = 10%2F4.827
Cross multiply
4.827t = 10 * 25
t = 250%2F4.827
t = 51.8 min to run 10 km
