Need average time on all requests by priority need to close\resolve request

like

Low priority - 20 requests - 2days 23:00 all time - 10:00 hours average time 

Normal - 5 req - 05:50 all time - 0:50 mins average time 

High - 10 req - 12:35 all time - 01:05 min average time 

if can't make this report in one, need two different with all time spent to resolve requests by priority and average time spent to resolve requests by priority
