Use ( minutes ) x ( hours / minute ) = hours
to change units
+20%2A%281%2F60%29+=+1%2F3+
So, +20+ minutes is +1%2F3+ hrs
----------------------
Now convert +2+ hrs to one-thirds of an hour
+x%2F3+=+2+
+x+=+6+
So, +6%2F3+=+2+ hrs
Adding up, I have +6%2F3+%2B+1%2F3+=+7%2F3+ hrs
-----------------------
Use +d+=+r%2At+
+d+=+65%2A%287%2F3%29+
+d+=+455%2F3+
+d+=+151.667+ miles
