For at least 50 km:
+s%28t%29+=+50+ km
+50+=3t+%2B+47+
+3t+=+3+
+t+=+1+ hr
--------------
For a maximum of 53 km:
+s%28t%29+=+53+
+53+=+3t+%2B+47+
+3t+=+6+
+t+=+2+ hrs
-----------
the minimum number of hours
for which Alan can drive his car
is 1 hr
-------
the maximum number of hours
for which Alan can drive his car
is 2 hrs
