Staff Review
This video takes the idea of writing and solving equations to figure out how long it takes to do a job, and it spins it a little. This time, you know the time it takes one person and the time it takes together, and you have to figure out how long it would take the other person alone. This could be very confusing, but this video makes it very clear.
