So we wan't to see how long would it take to clean 5 showers if the time it takes to clean one shower is 5.22 mins. Lets say that the complete time that it takes to clean all showers is equal to x. then x would be: x=5*5.22mins. So we get: x=26.1 min. So the time it takes to clean all 5 showers is 26.1 mins.
