The interest rate formula is Interest Rate = (Simple Interest × 100)/(Principal × Time).
How do you solve rate problems?
All rate problems can be solved by using the formula D = R(T), which translates to distance (D) equals rate (R) multiplied by time (T).
What is rate and example?
The definition of a rate is a quantity measured and compared to another quantity measured (such as a number of miles per hour) or is the cost of something. An example of a rate is being paid $10 per hour. An example of a rate is the price of gas. A rate of speed of 60 miles an hour.
