3. Formulas
1. Distance Formula: D = rt; where r = rate (speed) and t = time
3. Area of a Square:
Since each side is the
same length, P = 4S
2. Perimeter of a Square:
If you drive for 2 ½ hours and average 50 miles per hour,
how many miles have you driven?
If you drive 120 miles in 2 ½ hours, what is your average
speed?
A 150 mile trip at 60 mph, would take how long?
Area = LxW, but since each side is the same length, we are
multiplying a number times itself. So the formula is:
Area of a square = S2

4. Class Notes
