or if you divide it would be 5.5
The number of time it would take Todd to paint the room alone is 15 hours.
- Let the Todd's time be t.
<u>Given the following data:</u>
To calculate the number of time it would take Todd to paint the room alone:
How to solve a word problem:
In order to solve this exercise, we would first of all calculate their individual rate and combined rate respectively. Finally, we would add their individual rates together and equate it to the combined rate.
<u>For </u><u>Sue</u><u>:</u>

<u>For </u><u>Jeff</u><u>:</u>

<u>For </u><u>Todd</u><u>:</u>

<u>Combined rate:</u>

Adding the individual rates, we have:

Multiplying all through by 120t, we have:

t = 15 hours.
