| Exercise Name: | Rate problems 2 |
| Math Missions: | Pre-algebra Math Mission |
| Types of Problems: | 1 |
The Rate problems 2 exercise appears under the Pre-algebra Math Mission. This exercise works with direct and inverse variation in the form of rates.
Types of Problems[]
There is one type of problem in this exercise:
- Find the solution to the rate problem: This problem has a ratio of three quantities, two that vary directly and two that vary inversely. The student is asked to use an initial condition to find the solution to another problem assuming similar rates.
Find the solution to the rate problem
Strategies[]
Knowledge of direct and inverse variation is useful for completing this exercise.
- If the people involved and the number of jobs completed stay equal to each other, the time will remain the same as the initial given situation.
Real-life Applications[]
- There are many applications of direct variation in business (revenue).
- There are many applications of inverse variation in physics (gravitation).
