Answer:

40.3miles/hr

Step-by-step explanation:

Given parameters:

Time taken  = 40min

Distance covered  = 27mile

Unknown:

Speed in miles per hour = ?

Solution:

Speed is the distance divided by the time;

   Speed  = [tex]\frac{distance }{time}[/tex]

convert the time to hrs;

               60min  = 1hr

                40min  = [tex]\frac{40}{60}[/tex]   = 0.67hr

Insert the parameters and solve;

        Speed  = [tex]\frac{27}{0.67}[/tex]   = 40.3miles/hr
