Answer:

Callie and Galen.

Step-by-step explanation:

Find out how many seconds it take for their heartbeat to beat one time.

166 ÷ 120 = 1.383 (Aaron)

88 ÷ 60 = 1.466 (Callie)

48 ÷ 30 = 1.6 (Emma)

22 ÷ 15 = 1.466 (Galen)

As you see, Callie and Galen's are equivalent.

  • R(-6,1)→R'(6,1);
  • S(-2,1)→S'(2,1);
