Book - 1.5 billion transport vehicles on the world's roads
Discover the numbers behind cars, planes, trains and rockets - from the teeny tiny to the mindbogglingly massive! Do you know how fast a space rocket blasts through the sky? Or how deep under the sea submarines have ventured? How about the number of electric cars on the road? Or the top speed of NASA's crawler transporter (hint - it's not very fast!) Discover the answers to all these questions and much more in The Big Countdown: Transport. Helping readers to visualise and understand numbers, The Big Countdown series looks at popular topics and investigates the great many numbers that make them fascinating. From the mind-bogglingly large to the smallest and most precious, this series helps us understand that it's not just our days that are numbered.
Ideal reading for number-crunchers aged 9 and up. 1st class post included.
