You can put this solution on YOUR website!
Let +d+ = distance from house to beach
+240+-+d+ = distance from house to park
Let +s+ = their speeds
————————————-
Jane’s equation:
+d+=+s%2A1.5+
Paul’s equation:
+240+-+d+=+s%2A2.5+
———————————
By substitution:
+240+-+1.5s+=+2.5s+
+4s+=+240+
+s+=+60+
There speed was 60 mi/hr
