Concept:
If we want to measure the average speed then we will need the distance covere by an object and also the time it will take to cover that distance.
Then we use the formula,
[tex]speed=v= \frac{distance}{time} [/tex]
Now,in our question
Distance=d=11.7 miles
Time=t= 15 min
[tex]speed=v= \frac{11.7 mile}{15 min} [/tex]
=0.78 mile/min
=0.8 mile/min
