Step 1

Convert mixed numbers to an improper fractions


4(1)/(2) =(4*2+1)/(2)= (9)/(2)


1(1)/(2) =(1*2+1)/(2)= (3)/(2)

Step 2

Find the unit rate of the descending


unit\ rate= ((9/2))/((3/2))=3 (inches)/(sec)

therefore

the answer is

the position of the spider relative to the surface after
1 second is
-3\ inches
