An old man walks for a distance of 450 m every day. What is the distance in kilometres and metres that he would walk in 1 week?
To convert 450 meters to kilometers, we divide by 1000:
450 meters = 450/1000 = 0.45 kilometers
So, the old man walks 0.45 kilometers every day.
In a week (7 days), the distance he walks is:
0.45 kilometers/day * 7 days = 3.15 kilometers
Therefore, the old man would walk a distance of 3.15 kilometers in 1 week.
To convert this distance back to meters, we multiply by 1000:
3.15 kilometers = 3.15 * 1000 = 3150 meters
So, the old man would walk a distance of 3.15 kilometers or 3150 meters in 1 week.
