In the first round, Lorelei did 3/4 * 180 jumps = <<3/4*180=135>>135 jumps.
In the second round, Hattie did 2/3 * 180 jumps = <<2/3*180=120>>120 jumps, while
Lorelei did 120 jumps + 50 jumps = <<120+50=170>>170 jumps.
The total number of jumps for the two in both rounds is 170 jumps + 120 jumps + 135 jumps + 180 jumps = <<170+120+135+180=605>>605 jumps
