The William's family used the sprinklers for 59 hours.

Because it used 25L per hour so 25/1 is 25 so then you multiply 1475 by 25 and you get 59

= used sprinklers for 59 hours.

The Taylor family used the sprinklers for 73.75 hours.

Because it used 20L per hour so 20/1 is 20 then you multiply 1475 by 20 and you get 73.75

= Used sprinklers for 73.75 hours.
