A car is being driven at a speed of 100 kilometres per hour

A man is walking at a speed of 200 centimetres per minute

Which one is going faster?

Unless you are able to convert units, all that you can do is look at the numbers and maybe conclude that the man is going faster because 200 is bigger than 100. But if you CAN convert, you would know that 200 cm per second = 720,000 cm per hour = 7.2 km per hour.
