The average speed you need to maintain is 0.33 miles per minute.
The average speed is the speed that you maintain throughout the journey. It is obtained as; Total distance covered/Total time taken
If we have the following information from the question;
Distance covered = 5 miles
Time taken = 15 mins
Then it follows that;
Average speed = Distance/time
Average speed= 5 miles/15mins
Average speed = 0.33 miles per minute.

Explanation:
Answer:
We show added energy to a system as +Q or -W
Explanation:
The first law of thermodynamics states that, in an isolated system, energy can neither be created nor be destroyed;
Energy is added to the internal energy of a system as either work energy or heat energy as follows;
ΔU = Q - W
Therefore, when energy is added as heat energy to a system, we show the energy as positive Q (+Q), when energy is added to the system in the form of work, we show the energy as minus W (-W).
