Answer 1

Answer:

84 km

Step-by-step explanation:

1.18*3 because first you need to know the distance covered by the duck in the first three hours

18*3=54

2.15*2 because you need to know the distance covered by the duck in the last 2 hours

15*2=30

3.now add 54 and 30 to get the distance covered by the duck in total

54+30=84

therefore the duck flew 84 km in all

just by the way-* means multiplied by or into
