Cory is at the park playing fetch with his dog. He throws the ball 23 m south, and his dog retrieves the ball and returns it to Cory. Cory then throws the ball 18 meters, and the dog again collects the ball and returns it to Cory. When the dog returns for the second time, what distance has the dog traveled?0 m82 m36 m23 m

Respuesta :

In order to determine the distance traveled by the dog in the two times, consider:

In the second time the dog goes and comes back for a distance of 18 m, that is, the total distance is 18m + 18m = 36 m

In the first time the dog goes and comes back for a distance of 23 m, that is, the total distance is 23m + 23m = 46 m

Hence, for the two times the distance traveled by the dog is:

46m + 36m = 82m
