Final answer:
Hector would take 40 minutes to walk the distance that Jane can walk in 20 minutes, as he takes double the time to cover the same distance.
Step-by-step explanation:
If Jane can walk any distance in half the time it takes Hector, and Jane takes 20 minutes to cover that distance, then Hector would take double the time to cover the same distance. Consequently, Hector would take 40 minutes to walk that distance because 20 minutes (Jane's time) multiplied by 2 equals 40 minutes.
Checking if the answer is reasonable is an important step. In the context provided, if you walk a certain distance in a specific period, such as 20 minutes, doubling the time would naturally result in double the duration, which is 40 minutes in this case. Therefore, the solution to how long Hector takes appears reasonable and consistent with the information provided.
