You can put this solution on YOUR website!
Find his rate in miles / hour
In terms of just units:
( miles / minutes ) x ( minutes / hour ) = miles / hour
+%28+y+%2F+20+%29%2A%28+60+%2F+1+%29+=+3y+ mi/hr
------------
Now do the conversion: ( minutes ) x ( hours / minute ) = hours
+15%2A%281%2F60%29+=+1%2F4+
Now use +d+=+r%2At+
+d+=+3y%2A%281%2F4%29+
+d+=+%283%2F4%29%2Ay+
