Based on your description, Rashad is experiencing moderate breathing and feels like he could sustain his current pace for a while. This typically corresponds to a moderate level of exertion on the RPE chart, generally around a level of 4 to 6.
However, since "4" and "6" are not provided in the options, and considering the context of the choices:
- 8 – This would indicate a very hard level of exertion.
- 2 – This would indicate very light exertion.
- 10 – This is maximum effort.
Given that Rashad feels he can sustain his pace, he is likely not at a high level, but neither is he at a very low level.
Therefore, if the options must be chosen, "2" would be too low, "10" too high, leaving 8 as the best approximation even if it feels slightly out of range for moderate exertion.
However, it's important to note that this might not perfectly match typical RPE readings. If forced to choose among the given options based on the context you've provided, I would pick 8, although I would advise that it's not a truly accurate reflection of a moderate effort.
