Due in a few hours.

Question

Carlo wants to use a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

Which rate is appropriate for describing the amount of water in this context?

millimeters per hour
grams per second
miles per hour
meters per second

I am feeling sick and this is due in a few days. Help Please.

Answer 1

MM/HR seems most appropriate, to me.  Although on the nightly news the rainfall is usually quoted as # inches per day.
