1. An AMTRAK train travels at 125 mph. Convert this into miles per minute.
2. The average speed of one team in a relay race is about 10 mph. What is this speed in feet per second?
3. The speed at which a certain computer can access the internet is 2 megabytes per second. How fast is this in megabytes per hour?

I'm just having some trouble with these q's. If you could include how you got the answer that would be wonderful. Thanks! (:
