Fa Sam le Harry ba na le diterata tsa legora tsa boleele jwa dikgato di le 100, mme ba dumalana go di kgaoganya ka gore Harry a bone dikgato di le 60 go feta Sam, go tla sala dikgato di le kae tsa ga Sam?

James decided to walk to the store.  When he got halfway there he realized he forgot something at home and had to walk back.  If his home is 4 miles from the store and he walks 4 miles per hour how long did it take him to reach the store?
A re re x ke palo ya dikgato tsa legora tse Sam a di bonang mme y ke palo ya dikgato tse Harry a di bonang. Re itse gore y = x + 60, mme gape y + x = 100.
Fa re tsenya equation ya ntlha mo equation ya bobedi, re bona gore 2x+60=100
Fa re ntsha 60 mo matlhakoreng oomabedi, re sala le 2x=40
Fa re arola tlhakore nngwe le nngwe ka pedi, re sala le x=20. Se se raya gore Sam o sala le dikgato tsa legora di le 20.

He walked 4/2=<<4/2=2>>2 miles there before turning around
So in total he walked 2+2+4=<<2+2+4=8>>8 miles, he walked 2 miles to the halfway point than 2 miles home.
That means it took him 8/4=<<8/4=2>>2 hours
