Austin washed 4 cars in 1 hour 40 minutes. How long will it takes to wash a car?
To solve this problem, we need to convert 1 hour 40 minutes into minutes.
1 hour is equal to 60 minutes, so we have:
1 hour 40 minutes = 60 minutes + 40 minutes = 100 minutes
Now, we divide the total time taken (100 minutes) by the number of cars washed (4) to find the time taken to wash a car:
100 minutes / 4 cars = 25 minutes
Therefore, it will take Austin 25 minutes to wash a car.
To find out how long it takes to wash one car, we need to divide the total time Austin took to wash 4 cars (1 hour 40 minutes) by the number of cars washed.
1 hour 40 minutes is equal to 1.67 hours (using the conversion: 60 minutes = 1 hour).
So, to find the time to wash one car, we divide 1.67 hours by 4 cars:
1.67 hours / 4 cars = 0.42 hours per car.
Therefore, it takes Austin approximately 0.42 hours to wash one car.
