a) 38.22
b) 3 mins 10 secs = 190 seconds
190 / 4 = 47.5 seconds per runner.

In 38.219, the 1 is in the hundredth place. Look at the number following it (9), is it above 5? Since it is, you round up: 38.22.
3 min 10 sec = 190 sec
190sec/4runners = 47.5 sec/runner (I don't know why they mentioned the length)

this pal is in want of a few extreme help. unfortunatly those with ingesting topics ( it truly is a range of bulemia that is merely pooping it out somewhat of throwing it up) are in many situations the perfect to note that they want help. start up off by telling her the data about laxative use. they are going to dehydrate you it truly is why it variety of feels that you're dropping weight, that is all water. and through the time the nutrition reaches your intestines and is expelled, your body has absorbed the energy besides. her maximum suitable wager is a pragmatic nutrition plan and excercise if she easily appears like she desires to drop extra pounds. if she maintains her undesirable health judgements, you would possibly want to tell someone. she might want to hate you for it on the time, yet an ex pal is extra useful than a useless pal.
