Well, since there are 52 cards in one deck, and he draws 1 card from it 39 times, there would be 13 cards left. Also, there is only one ace in a deck of cards. Either he drew the ace from the 39 cards he drew, or the ace is in the 13 cards he didn't draw. It's hard to say. I'm not too sure, I'm really sorry :(
Their speed of separation will be equal to the sum of their speeds because they are in opposite directions. Speed of separation = 40 + 50 = 90 miles per hour
Time = distance / speed Time = 405 / 90 Time = 4.5 hours <span />
