RT=D basic uniform travel rates rule to relate rate, time, distance

             rate          time        distances
train         177.8          x         177.8*x
bus            80            y         80*y
total                      5&11/80     900

Find two linear equations in the variables x and y; and you want a solution for the value of y.
