0.8 hours
1.7 hours
3.4 hours
7 hours

What is the time it takes Sanjay to complete the puzzle? 6 hours

What is the time it takes Felipe to complete the puzzle? 8 hours

We can use the general formula of rate and time to solve this problem. Generally we have,

Rate * Time = Work/Job

** where Work/Job for this problem is 1 since they are doing 1 work, which is solving a puzzle

Working together, their rate is the sum,

Total Rate = .

Using the general formula again, we can find the time it will take to solve the puzzle when both works together.

hours

Rounding the answer, we have 3.4 hours.
