By speed · Order from slowest to fastest.

1. A person walking 5 km/h

   The average person takes around 7,000 steps a day, walking the equivalent of several times around Earth in a lifetime.

2. A sprinting cockroach 5.8 km/h

   A cockroach can survive for weeks without its head, breathing through tiny holes along its body.

3. A running roadrunner 32 km/h

   Real roadrunners prefer sprinting to flying and can kill rattlesnakes, far from the cartoon's gentle dodging.

4. A fast cricket delivery 161 km/h

   The fastest bowlers can make the ball rise off the pitch toward a batter's head in a fraction of a second.

5. A helicopter at top speed 290 km/h

   A helicopter's top speed is capped because the blade tips would approach the sound barrier and lose lift.

6. The motorcycle land-speed record 640 km/h

   Streamlined record bikes look like rockets on wheels, with the rider lying flat inside a sealed shell.
