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.

Answer:

For the 1st one the answer is 2/3 x 1/2 = 0.333 repeating and the 2nd one is 3/5 x 1/3 = 0.2

Step-by-step explanation:

The amount of boxes in total is the denominator and the amount of boxes shaded is the numerator, so if you put those to together it creates a fraction. So multiply the first fraction and the second fraction and you get your answer.
