Yes when an eleven year old girl can do dash time in 78 seconds of 400m it is good timing. It really just depends on the health of the person and how good they are at doing it.
The men's world record in the 400 meter dash is 43.18 seconds. The men's world record in the 400 meter hurdles is 46.78 seconds. This is a difference of 3.60 seconds. The women's world record in the 400 meter dash is 47.60 seconds. The women's world record in the 400 meter hurdles is 52.34 seconds. This is a difference of 4.74 seconds.
about 60 seconds.
A good time i believe would probably have to be a 1:18:00 - 1:25:00... so a minute and 18 seconds to 1 minute and 25 seconds!! because there are so many 7th and 8th grade kids who run the 400m dash from 1:12:00 down to 55 seconds!!
A 400m dash is 0.4km.
12-15 seconds
Let's see.. For a 15 yr old boy a good 400m time would be 56-59 seconds. For a girl 64-66 seconds is better than average, 59-63 seconds is elite and anything that's 58 seconds and under is state material. For boys, state material is like 50 seconds and under. Hope that helps :)

It all depends on your age. If your in sixth grade, than: 31-33 If your in seventh grade, than: 28-30 If your in eighth grade, than: 26-28

1km = 1000m so the 1500m only
To train for the 400m dash you have to spend time on running long distances, and practise sprinting. because the 400m dsh is a bit if sprint, yet a bit of long distance. you will need to train for many years to win in the olympics. Probably about 10 or 15 years.
