You can put this solution on YOUR website!
You have 2/3 of the distance left. As long as your
speed is constant, you have +%282%2F3%29%2A%28+5+%2B+3%2F4+%29+ of
the time left. That is +10%2F3+%2B+2%2F4+=+3+%2B+1%2F3+%2B+1%2F2+
+3+%2B+1%2F3+%2B+1%2F2+=+3+%2B+2%2F6+%2B+3%2F6+
+3+%2B+5%2F6+ hrs
+%285%2F6%29%2A60+=+50+ minutes
You have 3 hours and 50 minutes left
