Answer:
Your heart rate is 1.1 beats per second. Your friend's heart rate is 1.2 beats per second. Yes, the rates have the same rate (bps).
Step-by-step explanation:
Your heartbeat = 22:20 (can be reduced to 11:10) or 22/20 = 1.1 bps
Friend's heartbeat = 18:15 (can be reduced to 6:5) or 18/15= 1.2 bps
