THe wheel has to cover 5 miles, right? So divide the 5miles by the wheel circumference to get the number of turns, and then divide by time.

If I understand the steps correctly, 27x 3.14= 84.78 divided by 5= 16.956 divided by 15= 1.1304 (which seems pretty slow) If you notice a mistake I have made in the procedure please let me know. Thanks

number of turns=5miles/(27inches*PI) Now, you have to convert miles to inches to divide this out. Then, after you get revolutions from the above, divide by 15 min to get rev/min

Pre-Calculus? I wonder what the question is. In a basic algebra course, you would be looking for zeroes, and probably get those by factoring. 2x^2+11x-21=0 (2x-3)(x+7)=0 x= 1.5, or x=-7

The Earth is not exactly a sphere, but your equation ought to be this: distance=radiusEarth*theta where theta is the angle in radians. In this case, the angle from the N pole is 90-36, or 54 degrees, and converting that to radians 54*PI/180= .942 radians distance=3963*.942 miles.

P=2(W+L) A=WL, so L = 180/W so, P = 2(W+180/W) This is pre-cal, so you don't have calculus at your disposal. But, you do know that a square has maximum area for a given perimeter. So, W = L = √180 = 6√5
