You can put this solution on YOUR website!
distance going = distance coming back
(speed*time going) = (speed*time coming back)
%28s+-+50%29%2A5+=+%28s+%2B+50%29%2A4.09
5s+-+250+=+4.09s+%2B+204.5
.91s+=+454.5
s+=+499.45 mph answer
check
%28s+-+50%29%2A5+=+%28s+%2B+50%29%2A4.09
%28499.45+-+50%29%2A5+=+%28499.45+%2B+50%29%2A4.09
449.45%2A5+=+549.45%2A4.09
2247.25+=+2247.25
OK
