Question 826470

_____________speed_______________time____________distance
Kathy________35__________________x_______________35x
Gilbert______45__________________y_______________45y
Total___________________________(8)______________337


Do you understand this table, and do you know what to do with the data shown?




---------
The totals allow making a system of two equations in the unknowns, x and y:
--------
x+y=8
--------
35x+45y=337
--------


Best way to handle is Elimination Method.  Multiply the time sum equation by 35, and subtract from the distance sum equation, and quickly get a value for y.
