Solving Work Problems

Don't forget to watch the Recording on Applications of Quadratic Equations (check Help Center channel)

Remember:

• Work is the product of force and distance

• Rate is the reciprocal of the time a person finished the job

• A work done is equivalent to one

• The time spent working together is ideally shorter than doing the job alone.

Solving Age Problems

Remember

• Be familiar on how to represent past, present and future ages

• Be familiar with the use of verbs that may serve as clue in translating a problem into an equation (e.g. His age was…- meaning past age)

Solving Distance Problems

Remember:

• Distance is the product of rate and time.

• Be familiar with different cases of distance problems – round trip, object moving in the same direction (overtaking) and moving in different directions
