An oil tanker aground on a reef is losing oil and producing an oil slick that is radiating out at a rate approximated by the function \[dr/dt=20/t√ when t \ge1\], where r is the radius of the circular slick in metres after t minutes. If the radius of the slick is 21 metres, after 15 seconds, find, to the nearest metre, the radius of the slick after 10 minutes.
