How to create a formula to divide a constant number in the number of tasks?

Hi Guys

which formula do I need do divide the number 90 which represent the total hours in a Sprint by the number of tasks in the sprint?
Ex: if I have 10 items in a sprint the result will be 9 per item

Hi @mirmelsh - are your tasks in a sprint represented as items or subitems?

hi @mark.anley they are set as items
