AI explanation

Using the formula Distance = Speed x Time, Alexander's distance is 20 multiplied by his total travel time T. Bennett's distance is 40 multiplied by his total travel time T - 1, because he leaves an hour later but arrives at the exact same moment. Because the value of T is never provided, the expressions 20T and 40T - 40 cannot be uniquely evaluated or compared. The relationship cannot be determined from the information given.
