Superman flew to ANOTHER universe in what looked like to be a few seconds. But let's say it took a few 3 minutes. I'm using light years. The observable universe is 91 billion light years in diameter.
Speed = Distance 
               -------------- =       91,000,000,000 
                Time                ------------------------- =   30,333,333,333
                                                   3                      ----------------------- =  286, 983, 666, 663, 510, 000, 000, 000, 000 m/s
                                                                               1 second 

That's 957, 274, 471, 072, 618, 000 times the speed of light!
