Answer:
The average speed on the return trip is 2.44 miles/h.
Step-by-step explanation:
To find the average speed we need to use the following equation:
[tex] \overline{v} = \frac{d}{t} [/tex]
Where:
d: is the distance
t: is the time
Since the question is to find the average speed on the return trip, we will take the data of the time and speed of only the return trip.
[tex]\overline{v} = \frac{d}{t} = \frac{5 + 1/2}{2 + 1/4} = 2.44 miles/h[/tex]
Therefore, the average speed on the return trip is 2.44 miles/h.
I hope it helps you!
