The speed of sound through air is around 1126 feet per second - above that it's SUPERSONIC - So what do you reckon the speed of sound is through water - faster or slower?

Driving my wee Honda back from the supermarket - through the local NZ scenic limestone country at around 100 kph (- something like 62 mph or 91 feet per second) - I mused on a recent story from LBC Radio - that the average speed of London's road traffic is recorded as 7.8 mph.(11.4 ft/sec).
I've always known why we left London in the first place - and migrated by Boeing 747 to New Zealand (at around 570 miles per hour = 836 feet per second or 920 km/h) with our young kids - but it is good to get some confirmation of my thinking.

- Now comes a reminder that America was very much built by the use of guns firing at close to the speed of sound.. In South Dakota, the Lakota Sioux tribes are steadfastly refusing to accept payment of around $1.2 Billion as "compensation" for the theft of the lands that the 1868 Treaty of Fort Laramie guaranteed them - “undisturbed use and occupation” - including the 'Black Hills', a resource-rich region of Western South Dakota.
A mere nine years after that Treaty - the land was taken away from the Sioux Nation because gold had been discovered.
- Here in New Zealand we similarly signed The Treaty of Waitangi with Maori Tribes in 1840 - and subsequently payments for Treaty breaches have consisted of hundreds of millions of dollars of reparations in cash and assets - as well as apologies.

The Speed of sound through pure water is roughly 4859 feet per second .. about 4.1 times faster than through air. - In Sea water it is around 4921 feet per second.
(in Air it's 1126 ft/sec)
