<1m/s=3,6km/h><Bạn cứ xài cái này thì oke>
1,5km/h=\(\dfrac{5}{12}\)(m/s)
20km/h=\(\dfrac{50}{9}\)(m/s)
0,5m/s=1,8(km/h)
1,5m/s=5,4(km/h)
\(\left[{}\begin{matrix}45\left(\dfrac{km}{h}\right)=12,5\left(\dfrac{m}{s}\right)\\20\left(\dfrac{m}{s}\right)=72\left(\dfrac{km}{h}\right)\\6\left(\dfrac{km}{h}\right)=100\left(\dfrac{m}{min}\right)\\\left[{}\begin{matrix}400\left(\dfrac{m}{min}\right)=24\left(\dfrac{km}{h}\right)\\3\left(\dfrac{km}{h}\right)=83,\left(3\right)\left(\dfrac{cm}{s}\right)\\\dfrac{750}{s}=\dfrac{km}{h}?????\end{matrix}\right.\end{matrix}\right.\)
a, 18km/h=5m/s
b,12m/s=43,2km/h
c,48km/h=\(\dfrac{40}{3}\approx13,33\)m/s
d,150cm/s=1,5m/s=5,4km/h
e,62km/h=\(\dfrac{155}{9}\approx17,22\)m/s=\(\dfrac{15500}{9}\approx1722,22\)cm/s
f,300000km/s=300000000m/s=1080000000km/h
Bạn bấm máy tính casio á ấn \(shift\rightarrow8\rightarrow20\)(20 hoặc 19) nha
muốn đổi về km/h về m/s thì chia cho 3,6
a).18km/h=5m/s
b)12m/s=.43,2km/h
c)48km/h=40/3m/s
d)150cm/s=540m/s=1944km/h
e)62km/h=223,2m/s=803,52cm/s
a 18km/h
b 43,2km/h
c 13.3m/s
d 1,5m/s=5,4
e 17,2m/s=1722,2cm/s
a) 18km/h
b) 43,2km/h
c) 13,3m/s
d) 1,5m/s = 5,4km/h
e) 17,2m/s = 1720cm/s

a. 0,05km/h=0,014m/s
b.0,055m/s=0,2km/h
c.1,5m/s=5,4km/h
d.200m/s=714km/h
e.14,4km/h=4,032m/s
<3,6km/h=1m/s>
36km/h=10m/s
108km/h=30m/s
15m/s=54km/h
20m/s=72km/h
12000m/h=\(\dfrac{10}{3}\)m/s
180m/min=3m/s
