Answer:

B) 19/30

Step-by-step explanation:

Se deben recorrer 5km en total, en números fraccionarios se recorren:

1er día:

1200m = 1.2km = 6/5km

2do día:

1 + 2/3km = 5/3km

3er día:

1.5km = 3/2km

La suma da:

6/5km + 5/3km + 3/2km = 36/30km + 50/30km + 45/30km = 131/30km.

5km son 150/30km.

150/30km - 131/30km = 19/30 km

La respuesta es:

<h3>B) 19/30</h3>
