Answer:

Time to store = \frac{1}{2}hr

Time from store  = \frac{2}{5}hr

Average speed  = ?

Solution:

Average speed is the total distance divided by the total time taken.

   Average speed  = \frac{total distance}{total time taken}  

Total distance  = distance to store + distance from store  = 5 + 5 = 10miles

Total time taken  =  \frac{1}{2}hr +  \frac{2}{5}hr = \frac{9}{10}hr

Average speed  = \frac{10}{\frac{9}{10} }   = 10 x \frac{10}{9}   = 11.1m/s
