<s>[INST] Gemma experiences a maximum heart rate of MRMH beats per minute on a stationary bicycle. We are also given that the ratio of actual heart rate to maximum heart rate while riding the bicycle steadily is 0.8. Since Gemma's actual heart rate is 160 beats per minute while riding the bicycle steadily, we can set up the equation to represent the ratio given:
e9780738668499_i0485.jpg , e9780738668499_i0486.jpg . As we solve the problem, notice that there is a restriction that MHRM cannot equal 160/0.8.
First, we multiply both sides of the equation by to get:
Then we multiply both sides of the equation by MHRM to get:
Since the ratio given restricts that the MHR cannot equal 0, we can divide both sides of the equation by 0.8 to solve for e9780738668499_i0489.jpg . (What would have happened if we divided by 160?[/INST]
