Answer:
- 1/3 hour per mile
- 3 miles per hour
Step-by-step explanation:
Time per mile can be found by dividing hours by miles:
(1/8 h)/(3/8 mi) = 1/3 h/mi
It will take him 1/3 hour to run 1 mile.
__
Miles per hour can be found by dividing miles by hours (or by finding the reciprocal of the above value):
(3/8 mi)/(1/8 h) = 3/1 mi/h = 3 mi/h
He could run 3 miles in one hour.

Answer:
A. (f-g)(x) = -5^x +3x -2
Step-by-step explanation:
The only terms that can be combined are the constants.
(f -g)(x) = f(x) -g(x)
(f -g)(x) = (-5^x -4) -(-3x -2) = -5^x -4 +3x +2
(f -g)(x) = -5x^4 +3x -2 . . . . . matches A
