96.43 mph to the nearest hundredth.

Answer:

Explanation:

-First, you have to find how many miles per minute the train goes.

You do this by dividing 45 by 28.

you get 45/28 miles per minute

-Then, you multiply 45/28 miles per minute by 60.

45 times 60 is 2700.

2700 divided by 28 is 675/7 which is:

Mixed number form: 96 and 3/7 miles per hour

rounded to the tenth: 96.4 miles per hour

rounded to the hundredth: 96.43 miles per hour

rounded to the thousandths: 96.429 miles per hour
