If you can be out of the airport quickly you can be in the city in 30 minutes. I'd visit Central Park (go skating), Rockefeller Center and/or Time Square (which most NYers hate but seems a must-do for kids.).
You'd have about 3 hours for this before you need to head back.
You are technically correct, but with two kids in tow, I think that would require planets to align absolutely perfectly. I think it's safer to assume 35-45 minutes just to get into Manhattan, let alone whatever time would be required to get to a destination IN the city. Trying to get to Central Park or Rockefeller Center or Times Square, for instance, will most definitely add meaningful time to the travel.
