You can put this solution on YOUR website!
Let +s+ = Ray's speed in mi/hr
+2s+%2B+10+ = Sue's speed
In 5 hours, Ray goes
+d%5B1%5D+=+s%2A5+ mi
In 5 hours Sue goes
+d%5B2%5D+=+%28+2s+%2B+10+%29%2A5+
+d%5B2%5D+=+10s+%2B+50+ mi
-------------------
+d%5B2%5D+-+d%5B1%5D+=+125+mi%0D%0A%7B%7B%7B+10s+%2B+50+-+5s+=+125+
+5s+=+125+-+50+
+5s+=+75+
+s+=+15+
+2s+%2B+10+=+2%2A15+%2B+10+
+2s+%2B+10+=+30+%2B+10+
+2s+%2B+10+=+40+
Ray's speed is 15 mi/hr
Sue's speed is 40 mi/hr
