Jelena is training at the track at her school. She does interval training, which means that she runs for some distance then stops to do other exercises. Each time around the track is called a lap. This is her training plan:
Run half of the way around the track, stop and do \(10\) push-ups.
Run three quarters of the way around the track, stop and do \(5\) burpees.
Run one and a quarter of the way around the track, stop and do \(15\) jumping jacks.
How many laps of the track has Jelena completed after doing the jumping jacks?
