*How far can a train travel in 45 minutes if it is traveling at 80 miles per hour?

53 miles

Step-by-step explanation:

80 miles per hour

x miles per 45 minutes

So, we know that an hour is 60 minutes so lets change the hour to that.

80 miles per 60 minutes

x miles per 45 minutes

Now, we do cross-multiplication:

So, we multiply 80 by 45 which is 3200. Then, we divide 3200 by 60 which is 53.3. So, the train travels 53.3 miles in 45 minutes.

But to round it, it would be 53 miles.

Hope this helps
