Answer:

Each person will wash all cars for 0.1875 hours

Step-by-step explanation:

One student takes time to wash all cars = 12

8 students take time to wash all cars = [tex]\frac{12}{8}= 1.5 hours[/tex]

So, 8 students together takes 1.5 hours to wash the car

Each person spent hours on washing all cars =[tex]\frac{1.5}{8}[/tex]

Each person spent hours on washing all cars =0.1875 hours

So, Each person will wash all cars for 0.1875 hours
