Step-by-step explanation:

1. Let's call <em>x</em> the height of the mast.

2. You know that the rope is attached to a point 6 feet from the base of the mast and the rope is 24 feet long, therefore, you can draw the right triangle shown in the figure attached.

3. To calculate <em>x</em>, you must apply the Pythagorean Theorem as you can see below:

x=\sqrt{(24ft)^{2}-(6ft)^{2}}\\x=\sqrt{540ft^{2}}

x≈ 23ft

If lisa can run a mile in 7 minutes. At that rate of speed, how long would it take her to run 2 kilometers?
murzikaleks [220]

Answer:

8.75

Step-by-step explanation:

1 mile = 1.6 km

So, every 7 minutes, 1.6 km is ran.

Divide 1.6 by 2 to figure out how much more she is running.

1.6 / 2 = 0.8

Divide the known pace by the extra distance to figure out the time

7 min / 0.8 km = 8.75 min
