Asafa Powell of Jamaica holds the men’s world record for the 100-m
sprint, with a time of 9.77 s.
Florence Griffith Joyner of the
United States holds the women’s
world record, with a time of 10.49

s.
What is the difference in their times?

50-38=12

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

0.038
