Question

Doug needs to fly some emergency serum from Yellowknife to Inuvik. He needs to do this flight in 4.5 hours. What average cruising speed will you recommend that he use in kilometers per hour? Justify your suggestion mathematically.

Answer 1

I recommend Doug to use an average cruising speed of d / t, where d is the distance from Yellowknife to Inuvik, and t is the allotted time of 4.5 hours. This results in an average cruising speed of d / 4.5 kilometers per hour.

Step-by-step explanation:

To determine the average cruising speed, we can use the formula:

Speed = Distance / Time

In this scenario, Doug needs to fly from Yellowknife to Inuvik in 4.5 hours. Let d represent the distance between the two locations. Therefore, the average cruising speed (Speed) can be calculated as d / 4.5 kilometers per hour.

To further justify this recommendation, consider that average speed is defined as the total distance traveled divided by the total time taken. In this case, Doug's objective is to cover a certain distance in a specified time frame, making the formula d / t appropriate for finding the average cruising speed.

By using this mathematical approach, Doug can efficiently plan his flight, ensuring that he maintains the required speed to reach Inuvik within the 4.5-hour limit. This calculation helps optimize the journey for emergency situations, ensuring timely delivery of the serum.
