1) Luis hizo una excursión de 20 km 75 hm 75 dam 250 m en tres etapas. En la primera recorrió 5 km 5hm, y en la segunda 1 km 50 dam más que en la anterior. a) ¿Cuánto recorrió en la tercera etapa? b) Expresa el resultado en metro

21500 m

Step-by-step explanation:

We will divide this point into four parts and we will pass it by the meter:

Total: (20 km * 1000 m / 1 km) + (75 hm * 100 m / 1 hm) + (75 dam * 10 m / 1 dam) + 250 m = 20000 m + 7500 m + 750 m + 250 m = 28500 m

First stage: (5 km * 1000 m / 1 km) + (5 hm * 100 m / 1 hm) = 5000 m + 500 m = 5500 m

Second stage: (1 km * 1000 m / 1 km) + (50 dam * 10 m / 1 dam) = 1000 m + 500 m = 1500 m

The value of the third stage would be the subtraction between the total and the first and second stage:

Third stage: 28500 m - 5500 m - 1500 m = 21.500 m

He traveled 21500 meters in the third stage

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
