Answer:
562.5 mph
Step-by-step explanation:
First, let's find how fast the car is going in miles per hour. We do this by dividing the miles by how many hours it took:
225/4 = 56.25
The car was going 56.25 mph
A high-speed train is ten times faster than this car so you multiply 56.25 by 10
(10)(56.25) = 562.5
The train's speed is 562.5 mph
