At the track meet, ervin won the 100-meter dash with a time of 12.45 seconds. landon finished second. landon's time contains a 4 with a value 1/10 the value of the 4 in ervin's time. what could be landon's time in the 100-meter dash?

60

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
