Rates

Muhtasari

A rate compares two different quantities, telling you how much of one thing there is for each unit of another. Speed in kilometres per hour, a wage in dollars per hour, a phone plan in cents per minute: all of these are rates, and they are everywhere in daily life and in the exam.

In this lesson you will learn what a rate is, how to read and use common rates, and how to handle the most important one of all in this syllabus: average speed. By keeping a clear eye on units, you will be able to switch between distance, speed and time with confidence and solve real journey problems.

Malengo

Use common measures of rate.
Solve problems involving average speed.

Maelezo ya Somo

Rates let you compare and predict. Knowing the price per litre tells you which fuel station is cheaper; knowing a typing rate tells you how long a document will take; knowing an average speed tells you when you will arrive. The single habit that makes rate questions easy is watching the units, and that habit pays off across science and everyday decisions too.
