Step-by-step explanation:
Student who gone from class within 3 sec = 12
within 1 sec, it would be 12/3 = 4
So, your answer is 4
If you would like to find the average of 132 1/2 and 137 2/3, you can calculate this using the following steps:
<span>132 1/2 = 265/2
137 2/3 = 413/3
</span>
132 1/2 + 137 2/3 = 265/2 + 413/3 = 795/6 + 826/6 = 1621/6
<span>1621/6 / 2 = 1621/12 = 135 1/12
</span>
The correct result would be <span>135 1/12.</span>
