Atrain traveling at a constant speed and has traveled 67.5 miles in the last 1.5 hours. which equation shows the proportional relationship between the distance, d and the time, t, that the train has traveled? d=67.5t d=69t d=50t d=45t

The equation which shows the proportional relationship between the distance, d and the time, t, that the train has traveled is:

                           d=45t

The distance traveled by train in 1.5 hours is:  67.5 miles.

As we know that the speed of the train is constant.

This means that the ratio of distance to speed is always constant.

i.e.

         Hence, the proportional relationship between distance and time is:

                            d= 45t

the square root of what number? if you add that, then someone will probably answer the question.
