The drive motor of particular CD player is controlled to rotate at a speed of
240 rpm when reading a track 5.4 centimeters from the center of the CD. The speed of the drive motor must vary so that the reading of the data occurs at a constant rate. Find the linear speed (in cm/sec) of the drive motor when it is reading a track 5.4 centimeters from the center of the CD. Round your answer to the nearest integer.
Please enter your answer as a number without the units.
-----------------
A tire for a compact car is 20 inches in diameter. If the car is travelling at a speed of 55 mi/hr, find to the nearest integer the number of revolutions the tire makes per minute.
Please enter your answer as a number without the units.
------------------------------
How many revolutions will a car wheel of diameter 55 cm make as the car travels a distance of 4 km? Please round the answer to the nearest hundredth.
---------------------------------------
The distance between two points and on Earth is measured along a circle having center at the center of Earth and radius equal to the distance from to the surface (see the figure). The diameter of Earth is approximately 8000 miles. If angle has measure 1', then the distance between and is a nautical mile. Approximate the number of land (statute) miles in a nautical mile.
