To find out how far the duck swims in four weeks, we can follow these steps:
-
Calculate the distance swum in one day:
- The pond is 36 m long.
- The duck swims 4 lengths of the pond each day.
- Distance swum in one day = 4 lengths × 36 m = 144 m.
-
Calculate the total number of days in four weeks:
- There are 7 days in a week.
- Total days in four weeks = 4 weeks × 7 days/week = 28 days.
-
Calculate the total distance swum in four weeks:
- Total distance = distance swum in one day × number of days.
- Total distance = 144 m/day × 28 days = 4032 m.
Thus, the duck swims a total of 4032 meters in four weeks.
