A relativity question regarding the speed of light

[Zylstra]

<i>
</i>Given: dL = l' / l; dT = t'/t; v/c = 0.8
l' = a length observed by the moving frame
l = the same length observed by the static frame
t' = a time observed by the moving frame
t = a time observed by the static frame 

Find dL and dT

Lorenz time and length dilation equations:
l' = l*sqrt(1-pow(v/c, 2))
t' = t/sqrt(1-pow(v/c, 2))

dL = l*sqrt(1-pow(v/c, 2))/l
dL = sqrt(1-pow(v/c, 2))
(t' = t/dL)
dL = sqrt(1-pow(0.8, 2))
dL = sqrt(1-0.64)
dL = sqrt(0.36)
dL = 0.6
dT = (t/dL)/t
dT = 1/dL
dT = 1.667_
