Acoyote can run up to 43 miles per hour while a rabbit can run up to 35 miles per hour. write two equivalent expressions and then find how many more miles a coyote can run in six hours then a rabbit at these rates.

So, the coyote can run up to 43 miles per hour, 43 times 6 = 258 miles.  
The rabbit can run up to 35 miles per hour, 35 times 6 = 210 miles.
Now you will minus the 258 and the 210 and that is 48. 
The coyote ran 48 miles more in the same amount of time as the rabbit did.

This does not make sense
