1 litre of solution needs to be given over 10 hours. How many mls/ and hour should be given?

To find out how many mls/hour should be given, we need to first determine how many mls should be given in 1 hour.

Given that 1 liter of solution needs to be given over 10 hours, we first convert 1 liter to mls:

1 liter = 1000 mls

Next, we calculate how many mls should be given per hour:

mls per hour = Total mls / Total hours

mls per hour = 1000 mls / 10 hours

mls per hour = 100 mls/hour

Therefore, 100 mls should be given per hour.

\boxed{100 \, \text{mls/hour}}
