At the car dealership, one person can clear a car in 3 hours. Another person can clean that same car in 4 hours. Which equation can be used to find the total time, t, in hours, it will take the two people to clean one car by working together?

The value of time required to clean the car by both persons working together = 1.714 hours

Step-by-step explanation:

Time taken by first person to clean the car = 3 hours

Time taken by second person to clean the car = 4 hours

Time taken by both persons to working together  T =

Put the values of &  in above formula we get,

⇒ T = hours = 1.714 hours

This is the value of time required to clean the car by both persons working together.
