Hey guys,

Today, I learned about locomotion, which means the ability to move from one place to another. A normal human can run at a speed of 8–12 km/h, while a cheetah can run up to 120 km/h. However, it can only maintain that speed for a few kilometers.

In ancient times, when there were no cars, people used horses because they had the muscles to run at 70 km/h continuously. A cheetah can’t do this because it doesn’t have the same type of muscles—and the same goes for us humans.

The first car ever made could only go 16 km/h at its maximum speed, while a horse could go 70 km/h. So, back then, buying a car was kind of a waste because horses were faster. But eventually, we reached and even passed the speed of a cheetah.

Nowadays, a normal airplane can go 800 km/h, and the fastest airplane can reach 7,274 km/h. That means, back when there were no airplanes, if we had to travel from Dubai to India by car, it would take approximately 15 days. Now, thanks to airplanes, we can reach our destination in just 3 hours.

Here’s a table showing the maximum speeds of different animals, humans, and vehicles:
