112.5 seconds per lap. As you need to convert the minutes to seconds, 7 x 60 = 420 + 30 = 450
450/4 = 112.5
(10x-20)= (6x+8) subtract 6 from each side
(4x-20)=(+8) add 20 to each side
(4x)=(28) divide both sides by 4
x= 7
Ab/ac = ae/ad = be/cd
4/ac = 6/15
6 ac = 60
ac = 60/6 = 10
ac = 10

The numerical length of CE is mathematically given as
Lde= 4
<h3>Determine the numerical length of CE.?</h3>
Generally, the equation for Line segment CE is mathematically given as
DE = (x+2),
CD = 3x+2,
CE = 5x+2
Therefore
DE = (x+2),
CD = 3x+2,
CE = 5x+2
CE =CD+DE
5x+2 = 3x+2 + x+2
5x =4x+2
x = 2
The lenght of DE
Lde= (x+2) = (2+2)
Lde= 4
In summary, the numerical representation of the length of DE is 4.
