Hello, I come from the French Server, so my English is.....
![\frac{212}{6} =35,33333333333333...](https://tex.z-dn.net/?f=%20%5Cfrac%7B212%7D%7B6%7D%20%3D35%2C33333333333333...)
So the answer is b) 35,33 km/h.
I asked my brother and he said it was 12. I don’t know if he’s right but I hope it is ;)
of his journey he still has to complete .
<u>Step-by-step explanation:</u>
Here we have , A salesman traveled 2/5 of his journey before lunch and 3/8 of his journey after lunch. We need to find What fraction of his journey has he still to complete . Let's find out:
Let , total journey of salesman to travel be x . So , A salesman traveled 2/5 of his journey before lunch and 3/8 of his journey after lunch . Let , y be the fraction of his journey has he still to complete . So , According to question:
⇒ ![y+\frac{2x}{5} +\frac{3x}{8} =x](https://tex.z-dn.net/?f=y%2B%5Cfrac%7B2x%7D%7B5%7D%20%2B%5Cfrac%7B3x%7D%7B8%7D%20%3Dx)
⇒ ![y+\frac{2x(8)+3x(5)}{5(8)} =x](https://tex.z-dn.net/?f=y%2B%5Cfrac%7B2x%288%29%2B3x%285%29%7D%7B5%288%29%7D%20%3Dx)
⇒ ![y+\frac{16x+15x}{5(8)} =x](https://tex.z-dn.net/?f=y%2B%5Cfrac%7B16x%2B15x%7D%7B5%288%29%7D%20%3Dx)
⇒ ![y+\frac{31x}{40} =x](https://tex.z-dn.net/?f=y%2B%5Cfrac%7B31x%7D%7B40%7D%20%3Dx)
⇒ ![(y+\frac{31x}{40} )-\frac{31x}{40}=x-\frac{31x}{40}](https://tex.z-dn.net/?f=%28y%2B%5Cfrac%7B31x%7D%7B40%7D%20%29-%5Cfrac%7B31x%7D%7B40%7D%3Dx-%5Cfrac%7B31x%7D%7B40%7D)
⇒ ![y=\frac{40x-31x}{40}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B40x-31x%7D%7B40%7D)
⇒ ![y=\frac{9x}{40}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B9x%7D%7B40%7D)
Therefore ,
of his journey he still has to complete .
