A currency trader at the Boston airport has a buy rate of 1.3062 and a sell rate of 1.7484 for dollars per pound. Assume that a U.S. tourist returns from the U.K. and wants to sell 1,000 pounds. Five minutes later a U.S. tourist that is on his way to the U.K. comes to the same trader and wants to buy 1,000 pounds.
