Calc Larklight - Larklight flies to Earth

Larklight said:

Looking back, it's a bit of a bore in some ways that I was stuck down in the boiler room all through that miraculous journey, and didn't get a chance to peep out of a window as we sped across thirty thousand miles in the space of a few seconds.

Larklight flies 30,000 miles (48280.32km) in the span of a few seconds. We'll have a low end of 10 seconds, and a high end of 3 seconds.

(Low end)
T = 48280.32km/10s
= 4828032/340.29
= Mach 14187.9926

(High end)
T = 48280.32km/3s
= 16093440/340.29
= Mach 47293.3086

Final Results
Larklight flies to Earth (low end) = Mach 14187.993
Larklight flies to Earth (high end) = Mach 47293.309

And the power of it's gravity engines risked tearing the Moon apart just by flying by.

Alas,' said Mother, 'it would be far too dangerous. Larklight's machineries are designed for manoeuvring planets and moons about, not squashing spiders. I risked ripping the dear old Moon in half when I used them to bring us here. To unleash them upon Hyde Park might lead to a most terrible disaster.'
