Not enough detail.
One way is the verbal Rating of perceived exertion scale 6-20
Another is heart rate range compared to their Max heart rate 220-age
True I think it might be but at the same time it just depends on the distance
english--I learned that Jericho was Stripped of his clothes and then beated almost dead. Then a priest was coming down that road and he saw him and went a different way so that he doesn't have to deal with the guy. Then a Levite who was walking by that place, saw him and also made a detour and ignored Jericho. While a Samaritan who walked that way came to him, and when he saw him he helped him. He was nice he wanted to help. He bandaged his wounds and poured oil and wine to kill the infection. Then he helped him up and put him onto his horse and they road back to an inn. Then he got a reward for his kindness.
Spanish--Supe que Jericho fue despojado de su ropa y luego golpeado casi hasta morir. Luego, un sacerdote venía por ese camino y lo vio y tomó un camino diferente para no tener que lidiar con el tipo. Entonces un levita que pasaba por ese lugar, lo vio y también se desvió e ignoró a Jericó. Mientras que un samaritano que caminaba por ese camino se le acercó, y cuando lo vio lo ayudó. Era agradable, quería ayudar. Se vendó las heridas y vertió aceite y vino para matar la infección. Luego lo ayudó a levantarse y lo subió a su caballo y regresaron a una posada. Luego recibió una recompensa por su amabilidad.
