Question

Sylvia swam 930 meters in the pool each day for 3 weeks. How many kilometers did Sylvia swim in those 3 weeks

Answer 1

the answer is 19.53 kilometers

first we need to figure out how many days sylvia went to the pool.
there are 7 days in a week but we need to know how many days are in 3 weeks.
so multiply 7x3, which is 21

next multiply 930 by 21
930x21 = 19,530

finally we need to change meters to kilometers

19,530 meters = 19.53 kilometers
