Question

A car was driving for 4 hours and covered 225 miles. A high-speed train is ten times as fast as this car. Find the train's speed.

Answer 1

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

Hope this helps!
