The reason why Sam was incorrect is because he divided the Ciara's speed by the time taken to walk the distance.
What is distance?
Distance can be defined as the amount of ground covered by a physical object, regardless of its direction, starting or ending point.
How to calculate the distance walked?
Mathematically, the distance walked by Ciara should be calculated by using this formula:
Distance = speed × time
Distance = 49 × 40
Distance = 1,960 miles.
Therefore, we can logically conclude that Sam was incorrect.
