Note that \(\log(a)-\log(b)=\log(\frac{a}{b})\)
Multiply m^2 by 10^-4 to get hectares.
Like so:
Sequence: \(\frac{1}{8}, \frac{1}{8}+d, \frac{1}{8}+2d, \frac{1}{8}+3d, \frac{1}{5}\)
Last term: \(\frac{1}{8}+4d=\frac{1}{5}\) Use this to find d, then you can find and sum the three middle fractions.
You can write \(e^{i\theta}=\cos \theta+i\sin \theta\), so the real part of each number (a, c and f) is obtained using \(\cos \theta\) and the imaginary part (b, d and g) using \(\sin \theta\).
As follows:
The following gives a possible solution, subject to some assumptions:
90 km/h = 25 m/s
relative speed: lynx-rabbit = (25 - 18) m/s = 7 m/s
Time for lynx to catch rabbit = 20/7 s ≈ 2.9 s
So rabbit will get to burrow before lynx catches it.

Wow! You have a strange concept of "fun" Melody!! I don't think I would have found it fun at all.
