Which method should Ahmed use to effectively send a copy of the budget if time is a priority?

Choosing to send the budget by courier is the most effective method when time is a priority, despite its higher cost compared to other options. This method ensures the budget will arrive within 24 hours, which is significantly faster than the other choices. For instance, sending it by aeroplane, while quicker than the courier, may not be as viable due to its higher cost and the total travel time of 6 hours, which does not include any dispatch times and potential delays.

Local mail, although the cheapest option, would take 72 hours, which does not meet the urgency requirement. Similarly, sending it by hand via train takes 32 hours and incurs a higher cost than the courier service. Therefore, the courier option balances a reasonable cost with a timely delivery, aligning best with the need to prioritize speed in sending the budget.
