A constant rate means something changes at the exact same speed or amount all the time, never getting faster or slower. For example, if you pay $10 every month for a subscription, that's a constant rate.
Driving at a constant rate of 50 kilometres per hour means you travel 50 kilometres every single hour.

Try this analogy: A constant rate is like walking at a steady pace, where each minute you travel the exact same distance.
Ask your child: If a car is on cruise control, what is staying the same?
