Answer:

PQ = 16

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos60° = \frac{1}{2}, then

cos60° = \frac{adjacent}{hypotenuse} = \frac{RQ}{PQ} = \frac{8}{PQ} = \frac{1}{2} ( cross- multiply )

PQ = 8 × 2 = 16

Answer:

It will take Josie 80 minutes to run 10 miles.

Step-by-step explanation:

We can set up a proportion between the number of minutes she runs to the number of miles she runs. From what we know in the equation, we know that it takes her 24 minutes to run 3 miles, and it takes x minutes to run 10 miles. We can represent this in a proportion!

We know that the ratio of 24:3 will be the same for any number of miles, so we can say

\frac{24}{3} =\frac{x}{10\\}

We can solve this by first simplifying the left hand side then isolation x by multiple both sides of the equation by 10.

24/3 = 8

8 = \frac{x}{10}

80 = x

It will take Josie 80 minutes to run 10 miles.
