example:
Change the minutes into seconds.
No. of Minutes (m)  1  2  3  4  5  6  7  8 
No. of Seconds (s)  60  120  180  240         
Find the missing numbers in the table and construct the formula.
Solution:
When m = 1, s = 60
m = 2, s = 120
m = 3, s = 180
m = 4, s = 240
We observe a pattern in the values of (m and s) and we get the formula s = m*60.
Using above formula we can find the missing numbers.
When m = 5 Þ s = 5 * 60 = 300
m = 6 Þ s = 6 * 60 = 360
m = 7 Þ s = 7 * 60 = 420
m = 8 Þ s = 8 * 60 = 480
Directions: Construct the formula for the following problems. Also write at least 5 examples of your own.
