Answer 2

[Five centimeters per second]

\(P=\frac{3^9\cdot3^{20}\cdot2^8}{3^{24}\cdot243\cdot2^6}\)

\(P=\frac{3^{29}\cdot2^8}{3^{29}\cdot2^6}\)

\(P=2^2=4\)

\(Q=\frac{2^{15}\cdot5^3\cdot2^6\cdot3^4}{8\cdot2^{18}\cdot81\cdot5}\)

\(Q=\frac{2^{21}\cdot5^3\cdot3^4}{2^{21}\cdot3^4\cdot5}\)

\(Q=5^2=25\)
