Answer:

200 mph (321.87 km/h)

Step-by-step explanation:

If a train travels 400 miles in two hours, it would travel half of that in one hour (
400 ÷
2) which is 200 miles. To convert mph to km/h, just multiply by 1.61 (to be exact, 1.60934).

The speed is:

speed = 200 mph

Work/explanation:

To find the train's speed, we use the formula:


\large\textsl{$Speed=(distance)/(time)$}

In our case, the distance is 400 miles, and the time is 2 hours.

So, I plug in the data:


\large\text{$Speed=(400)/(2)$}


\large\text{$Speed=200\:mph$}

Hence, the train's speed is 200 mph.
