Atrain travels 30 miles in 1/3 hour at a constant speed is going faster than a train that travels 20 miles in 1/2 hour at a constant speed. explain or show why?

Because the speed of the train that  travels 30 miles in hour is greater than the speed of the other train.

See explanation.

Step-by-step explanation:

The formula to find the constant speed is:

Where "V" is the constant speed, "d" is the distance and "t" is the time.

Knowing that a train travels 30 miles in hour at a constant speed, we can identify that:

[texd=30\ mi\\t=\frac{1}{3}\ h[/tex]

Substituting these values into the formula, we get that the constant speed of this train is:

The other train travels 20 miles in hour at a constant speed, then we can identify that:

[texd=20\ mi\\t=\frac{1}{2}\ h[/tex]

Substituting values into the formula, we get that the constant speed of the this train is:

Since , we can conclude that the train travels 30 miles in hour at a constant speed, is faster than the other train.
