Noah is training for a swim meet and swims 500 meters each day. how many kilometers does does noah swim in a week if he trains every day

Knowing Noah swims 500 meters each day, we write:
500
To find out how many kilometers Noah swims in a week, we must first find out how many meters he swims in a week.
There are 7 days in a week, thus we multiply 500m by 7:
500 · 7
Simplify:
3500
Knowing there are 1000 meters in a kilometer, we can divide 3500 by 1000:
3500 ÷ 1000
Simplify to receive our final
3.5 Kilometers
