To solve this problem, we can use a proportion to find the distance the runner can go in 16 minutes.
We know that the runner completes 14 of a 5-mile race every 8 minutes. So, the ratio of the distance covered to the time taken is 14/8.
We can set up the proportion:
(14/8) = (x/16)
To find x, we can cross multiply and solve for x:
8x = 14 * 16
8x = 224
x = 224/8
x = 28
Therefore, the runner can go 28 miles in 16 minutes.

To solve this problem, we can set up a proportion to find the distance the runner can go in 16 minutes.
We know that the runner completes 1/4 of a 5-mile race every 8 minutes. So, the ratio of the distance covered to the time taken is (1/4)/8.
We can set up the proportion:
(1/4)/8 = x/16
To find x, we can cross multiply and solve for x:
(1/4)*16 = 8*x
4 = 8*x
x = 4/8
x = 1/2
Therefore, the runner can go 1/2 mile in 16 minutes.

My apologies for the confusion. Given that the original response options are 1/10 mile, 1/8 mile, 2 1/2 miles, and 160 miles, we can use the given information to determine the distance the runner can go in 16 minutes.
The runner completes 1/4 of a 5-mile race every 8 minutes. So, in 16 minutes, the runner would complete 2/4 (or 1/2) of the 5-mile race.
Therefore, the runner can go 1/2 mile in 16 minutes.
The answer that matches 1/2 mile is not provided in the options given.

To solve the expression (−2)×(1/5)÷(2/3)×(−5/6)÷(3/4), we need to follow the order of operations, which is known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Step 1: Simplify any multiplication or division within parentheses or brackets.
There are no parentheses or brackets in this expression, so we can skip this step.
Step 2: Simplify any exponents.
Again, there are no exponents in this expression.
Step 3: Simplify any multiplication or division from left to right.
Starting from left to right, we have:
First, multiply (−2) and (1/5) to get: −2 * 1/5 = −2/5.
Next, divide the result by (2/3) to get: −2/5 ÷ 2/3.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So, we invert (2/3) to get (3/2), then multiply:
−2/5 * (3/2) = −2 * 3 / (5 * 2) = −6/10 = −3/5.
Next, we have to multiply the result by (−5/6):
−3/5 * (−5/6) = 3 * 5 / (5 * 6) = 15/30 = 1/2.
Finally, divide by (3/4):
1/2 ÷ (3/4).
Again, to divide fractions, we multiply by the reciprocal:
1/2 * (4/3) = 1 * 4 / (2 * 3) = 4/6 = 2/3.
Therefore, the answer is 2/3.
So, the correct answer is D.
