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.
Answer:
4 students needed
Step-by-step explanation:
We can divide 5/6 and then round it to the nearest tenth which is 0.8.
This means every 0.8 hours 1 student is completed with their work.
We can then divide 3 hours with the 0.8 hours to get 3.75 students additionally needed to cut the time to 3 hours.
Obviously, we can't have 3/4's of a student so we convert that into 1 student, ending up with 4 students additionally needed to complete the work in 3 hours.
Mathematical work:
5 students/6 hours
= 0.8 hours
0.8 hour/3 hours
=3.75 students
Round 3.75 to 4
4 students additionally needed.
Hope this helped.
