Sanjay and Felipe are putting together a 500-piece puzzle. Sanjay could do the entire puzzle by himself in 6 hours, while it wou
Nata [24]

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,

<em><u>Rate * Time = Work/Job</u></em>

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


  • <u>Finding rate of Sanjay:</u>

R(6)=1\\R=\frac{1}{6}

  • <u>Finding rate of Felipe:</u>

R(8)=1\\R=\frac{1}{8}


Working together, their rate is the sum,

Total Rate = \frac{1}{6} + \frac{1}{8} = \frac{7}{24}.


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

(\frac{7}{24})T=1\\ T=\frac{1}{\frac{7}{24}}= \frac{24}{7} = 3.43 hours

Rounding the answer, we have 3.4 hours.


ANSWER: 3.4 hours
