Bella can rake the leaves in 3 hours and Jordan can complete the same task in 4 hours. If they work together, how long will it take Bella and Jordan to rake the leaves? Round your answer to the nearest hundredth of an hour.

Sagot :

Using the together rate, it is found that it will take 1.71 hours for Bella and Jordan to rake the leaves.

What is the together rate?

It is the sum of each separate rate.

In this problem, the rates are given as follows:

  • Together: 1/x.
  • Bella's: 1/3.
  • Jordan's: 1/4.

Hence:

[tex]\frac{1}{x} = \frac{1}{3} + \frac{1}{4}[/tex]

[tex]\frac{1}{x} = \frac{4 + 3}{12}[/tex]

[tex]x = \frac{12}{7}[/tex]

x = 1.71.

It will take 1.71 hours for Bella and Jordan to rake the leaves.
