Question

Va rog puteți rezolva aceasta problema de a 6?

Answer 1

Drumul=$24 \frac{2}{9} = \frac{218}{9}$ Km
1 ora= 12$\frac{1}{2}$ = $\frac{25}{2}$
2 ora=6$\frac{2}{9} = \frac{56}{9}$
[tex] \frac{218}{9} = \frac{25}{2} + \frac{56}{9}+ rest [/tex]
Amplificam prima fractie cu 2;apoi cu 9;cu 2;iar x (restul) cu 18
$\frac{436}{18} = \frac{225}{18}+ \frac{112}{18}+ \frac{18x}{18}$  <=>
436=225+112+18x
436=337+18x
x=$\frac{436-337}{18} = \frac{99}{18} =5,5 km$
