The answer is in the question itself... so since it says 20 miles per hour that’s the distance it covers per hour. the answer would be it travels 20 miles in an hour

Slow and steady wins the race. The leatherback sea turtle is the fastest known reptile, with a maximum speed of 21.9221.9221, po
topjm [15]

Complete question:

<em>The leatherback sea turtle is the fastest known reptile, with a maximum speed of 21.92 miles per hour (mph). </em>

<em>Which of the following equations, where d is distance in miles and t is time in hours, represents a speed that is less than that of the leatherback sea turtle? </em>

<em> </em>

<em>Select all that apply. </em>

<em>a.</em><em> d = 2.192t </em>

<em>b.</em><em> d = 20t </em>

<em>c.</em><em> d = 22t </em>

<em>d.</em><em> d = 30t</em>

<em />

Answer:

<em>a (2.192t) and b (20t)</em>

<em />

Step-by-step explanation:

Since units for distance and time are all measured in miles and hours respectively, we can simply compare the values of the options given with the leatherback turtle speed and express if the value is lower or not. We must pay special attention to the decimal separator in some cases.

<em />

<em>Leatherback sea turtle: </em><em>d = 21.92t</em>

<em>a.</em><em> d = 2.192t  </em><em>is less </em><em>than 21.92t</em>

<em>b.</em><em> d = 20t  </em><em>is less </em><em>than 21.92t</em>

<em>c.</em><em> d = 22t  </em><em>is more </em><em>than 21.92t   </em>

<em>d.</em><em> d = 30t </em><em>is more </em><em>than 21.92t</em>

Find the flow rate through a tube of radius 6 cm, assuming that the velocity of fluid particles at a distance r cm from the cent
vaieri [72.5K]

Answer:

791.68 cm/s

Step-by-step explanation:

The volume flow rate can be interpreted as the integral of fluid velocity over area

\dot{V} = \int\limits^6_0 {v(r) 2\pi r} \, dr\\\dot{V} = 2\pi\int\limits^6_0 {(25-r^2)r} \, dr\\\dot{V} = 2\pi\int\limits^6_0 {25r-r^3} \, dr\\\\\dot{V} = 2\pi[12.5r^2 - r^4/4]_0^6\\\dot{V} = 2\pi(12.5*6^2 - 6^4/4 - 12.5*0 - 0)\\\dot{V} = 2\pi*126 = 791.68 cm/s
