Taking the long view

Somebody at BBC News needs to reconsider their mathematical skills.

Most schoolchildren will tell you that 100 kilometres per hour is about 60 miles per hour. A cursory glance at a car speedometer would also reveal that fact.

From that, it's easy to work out that 10 km is about 6 miles.

Even if that's beyond you, just type '10000m in miles' into Google search and you'll get the answer.

See? Just over 6 miles.

Not surprisingly, the BBC's accuracy is miles out.
