Use +d+=+r%2At+
Going from A to B:
Convert +6+ min to hours
+d+=+60%2A%28+6%2F60+%29+
+d+=+6+ mi
---------------
At +50+ mi/hr:
+6+=+50%2At+
+t+=+6%2F50+ hrs
Convert hours to minutes
( hours )*( minutes/hour ) = minutes
+%28+6%2F50+%29%2A%28+60%2F1+%29+=+360%2F50+
+360%2F50+=+7.2+
It takes 7.2 minutes at 50 mi/hr
