Answer:

48 mph

Step-by-step explanation:

Distance = rate x time

Going: Rate is 60 mph      distance is 240  

The time is the \frac{Distance}{rate} or \frac{240}{60} or 4 hours.

Coming: Rate is 40 mph    distance is 240

The time is the \frac{distance}{rate} or \frac{240}{40} or 6 hours.

We can now find the average.

Average rate = \frac{total distance}{total time} = \frac{480}{10} = 48 mph

av =  \frac{v_{2} - v_{1}}{t_{2} - t_{1}}

t_{1} =  \frac{d}{v_{1}} =  \frac{240}{60} = 4 \: hours  \\ t_{2} =  \frac{d}{v_{2}}  =  \frac{240}{40}  = 6 \: hours

av =  \frac{v_{2} - v_{1}}{t_{2} - t_{1}}  =  \frac{40 - 60}{6 - 4}   =  \frac{ - 20}{2}  =  - 10

av  \: speed= 10 \\ av \: velocity =  - 10 \:  \: north
