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 ( ÷ ) which is 200 miles. To convert mph to km/h, just multiply by 1.61 (to be exact, 1.60934).
The speed is:
Work/explanation:
To find the train's speed, we use the formula:
In our case, the distance is 400 miles, and the time is 2 hours.
So, I plug in the data:
Hence, the train's speed is 200 mph.
