Answer:

1 If the equations do not involve fractions or decimals, and you have a good visual understanding of linear equations, graphing on the coordinate plane is a good option.

2 Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method.

3 Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.

Albert is walking twice ( 8/4) as fast as Kimbelry so Kimberley's speed is 1.5 yards per second.

So when Albert catches up he walks 6 + x yards while Kimberley has walked x yards.

x = 1.5t and 3t = 60 + x

3t = 60 + 1.5t

1.5t = 60

t = 60/1.5 = 40 seconds (answer)

So the time to walk 60 yards
