Answer:

177.03 s

Explanation:

A century dash is comprised by 100 meters. One mile is equivalent to 1609.34 meters.

If the runner is capable of running 100 meters in 11 seconds, his speed, in m/s, is:

$s = (100)/(11)\\s = 9.091\ m/s$

Assuming he keeps the same speed, the time that wil take him to cover one mile is:

$t=(1609.34)/(9.091)\\t=177.03\ s$

The runner takes 177.03 s to cover a mile.
