The most important variable is 4 miles per hour up hill. Down hill he can run 3 miles in the same time it takes time to run uphill.  up hill 4 miles  1 hour  so 2 miles up hill is 1/2 hour.  Down hill he can run 3 miles in the same time it takes time to run up hill..  2 miles up hill - 1/2 hour.  So 1/2 hr up and 1/2 hr down = 1 hour.

solong [7]

Answer:

20

Step-by-step explanation:

If you use PEMDAS(Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) you would take care of what's in the parentheses, so you would at 5 and 3 to get 8. Then you would multiply 6 and 4 to get 24, so far your equation looks like this 24 - 8 ÷ 2. You then divide 8 by 2 to get 4 then subtract 24 from 4 to get 20.
