Answer 1

Answer:

6.3 km.

Step-by-step explanation:

The question asks for kilometers, so all amounts have to be calculated in the same units -- kilometers.

Convert meters to kilometers.

600 m = .6 km

700 m = .7 km.

Add the amounts:

Fri.:       .6 km

Sat.     3 km

Sun.:   2.7 km.

--------------------------------

6.3 km.
