Answer:

Shah's training heart rate = 127.8 beats/min

shah's daughters training heart rate = 143.4 beats/min

Step-by-step explanation:

we know that both their resting heart rate is 60 (R=60)

so to find their respective maximum heart rate, put 60 into the M equation;

ie, for shar M = (220-A) Age = 47 given

so for shar m = 220-47 = 173

for her daughter m = 220-21 =199

Now we have this we can find the training heart rate which is by the equation, T = R + 0.6(M - R) we know both r and m.

for shar T = 60 + 0.6(173 - 60) = 60 + 0.6x113 = 60+67.8 = 127.8 beats/min

for her daugter T = 60 + 0.6(199-60) = 60 + 0.6x139 = 60 + 83.4 = 143.4 beats/min
