Question

A car wash machine cleaned 20 cars in 50 minuets at this rate how many minutes will it take the machine to clean 1 car

Answer 1

The machine will take 2.5 minutes to clean 1 car.

Step-by-step explanation:

To find the number of minutes it will take the machine to clean 1 car, we can use the concept of ratios. If the machine cleaned 20 cars in 50 minutes, we can set up a ratio:

20 cars / 50 minutes = 1 car / x minutes

Using cross-multiplication, we can solve for x:

20x = 50

x = 50 / 20 = 2.5 minutes

Therefore, it will take the machine 2.5 minutes to clean 1 car.

Answer 2

For this case what we should do is define variables:
x: time in minutes
y: number of clean cars
We then have the following equation:
y = (20/50) x
For 1 car we have:
1 = (20/50) x
Clearing x:
x = 50/20
x = 2.5 minutes
Answer:
It will take the machine to clean 1 car about:
x = 2.5 minutes
