To find the total work of two people at different speeds, we need to find a common speed limit to both.
In this case, Jordan can build a birdhouse in 2 hours so her speed is 1/2 birdhouse per hour.
For the sister, it takes 3 hours to build a birdhouse so her speed is 1/3 birdhouse per hour.
To find what they can do in one hour:
To find how long does it take to build a birdhouse:
Set the denominators equal:
Remove the denominators and solve:
Once again set the denominators equal:
Remove the denominators and solve for x:
6/5 hours is equal to 72 minutes.

Answer:
The missing exponent = power of 3
852.763 x 10³ = 852763
Step-by-step explanation:
The expression 852.763 x 10?
A number that is 1,000 times the value of 852.763 is calculated as:
852.763 × 1000 = 852763
Converting this to exponent
852.763 × 10³ = 852763
Therefore, the missing exponent that would result in number that is 1,000 times the value of 852.763 is power of 3 meaning 10³
