You can put this solution on YOUR website!
+d+=+r%2At+
+1+=+r%2A%28+r%2F60+%29+
Note that dividing by +60+ will convert
+r+ minutes back to hours
+1+=+r%5E2%2F60+
+r%5E2+=+60+
+r+=+7.746+ mi/hr
If you run at 7.746 mi/hr, you will
run 1 mile in 7.746 min
---------------------
check answer:
+1+=+7.746%2A%28+7.746%2F60+%29+
+60+=+7.746%5E2%0D%0A%7B%7B%7B+60+=+60+
OK
