I believe it would be 68 miles per hour! To find the unit rate here you would divide miles by hours, or 340 by 5, which would give you 68.
828.6 repeating (or 829 rounded up) feet per second.

<h2>
Explanation:</h2>
<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle
, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:

Finally, the height is:

Answer:
B. 7√10.
Step-by-step explanation:
√40 = √4√10 = 2√10
√90 = √9√10 = 3√10
So √40 + 2√10 + √90
= 2√10 + 2√10 + 3√10
= 7 √10.
(-2,-4) is the right answer because it makes sentence
