Answer: This means that Rick Hansen traveled around 50.56 km per day during his world tour.
Step-by-step explanation: To calculate the average number of kilometers Rick Hansen traveled per day on his world tour, we need to divide the total distance traveled by the number of days he was on the tour.
March 21, 1985, to May 22, 1987, is a total of 792 days (including the start and end dates).
Dividing 40,075 km by 792 days gives us approximately 50.56 km per day, on average. This means that Rick Hansen traveled around 50.56 km per day during his world tour.
