In my nutrition class,we say 60min. for children and teens. this can be anything! and doesnt have to be all at once. if your just trying to be healthy, 60min. is good. if you need to gain weight, you could do less/ or /if you need to lose weight, you could do more.
a hour every day.
A lab should get an hour to a half hour a day
your two year old should get 500 mg of calcium a day
947 a day
3 cups a day
3,000 kilometers
3.54 an hour if you work 24 hour a day for a whole year.
1 hour a day should suffice
well if you do an 8 hour day it is 600 a day and if you do a 5 day week it is 3000 a week and if you work a 52 week year it is 156000 a year.
most people like two pay around $2 an hour for non-professionals if you work more then 2-3 hours a day.
An eleven year old boy should have 2,300 mg a day
