The mean of the given numbers is 8.
Answer:
Two students will take 24 minutes to wash the car.
Step-by-step explanation:
In this case we can apply a rule of three to find out the time that will take for the students to wash the car. This has to be done such as:
3 students -> 16 minutes
2 students -> x minutes
3/2 = 16/x
But in this cases the problem states that this variables are inversely proportionate, which means that if there's less students washing the car they will take more time to finish the job. So we need to invert one of the fractions before computing the result.
3/2 = x/16
2*x = 3*16
x = 48/2 = 24 minutes.
Two students will take 24 minutes to wash the car.
The second option would be parallel
Number of jugs required to hold 18 gallons of water = 18/0.5
= 36
So 36 jugs are required by Jan to empty 18 gallons of water.
300 must be subtracted from the product of 25 and 23 to equal 275.
