450=60(8-x)+50x
Thank you so much for the equation - can u explain why we minus the 8 by x. I know it's the amount of time, can u clarify... thanks again
If I told you Ronald traveled 3 hours after noon, how long did he traveled before noon (given he traveled both before and after noon in 8 hours)?
5 hours
That is why it is 8-x. Do you understand?
yes i do now - thank you again - i can go to sleep now!! bye thanks
