25m/s=多少km/h 108KM/H等于多少M/s 4dm/min等于多少m/s

帮帮我吧，急急急急急急。而且必须要过程。O(∩_∩)O谢谢

Answer 1

1.90km/h=90*1000m/3600s=25m/s。
把1小时化成3600秒。

2.30啊
详细换算:1km=1000m,1h=3600s,1km/h=1000m/3600s=1/3.6(m/s),所以108除以3．6就等于30了！

3.

Answer 2

1km/h=1m/3.6h
25m/s=25*3.6=90km/h

108KM/H等于多少M/s
=108/3.6=30m/s

4dm/min等于多少m/s
4*10/60=2/3m/s

Answer 3

1km/h=1m/3.6h
25m/s=25*3.6=90km/h

108KM/H等于多少M/s
=108/3.6=30m/s

4dm/min等于多少m/s
4*10/60=2/3m/s
