Time/distance/speed
distance between train 1 and train 2 = 95 miles.
average speed of train 1 = 45 mph.
average speed of train 2 = 60 mph.
if both trains leave at the same time and travel toward each other but on parallel tracks, in how much time will their engines be opposite each other? (hint: when the engines are opposite each other, together the trains will have traveled 95 miles. their relative speed of travel is the sum of their respective speeds, or 105 mph.)

1/3 + 1/5 = 8/15.

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
