Dominic drove 324 miles from Salt Lake City,Utah, to Bryce Canyon National Park in 6 hours and 34 minutes. What was his average speed, in miles per hour?

6 hours and 34 minutes = 6.57 hours

324 / 6.57 = 49.3 mph

To find Dominic's average speed, we need to divide the total distance he drove by the time it took him.

First, let's convert the time it took him to hours. Since there are 60 minutes in an hour, we divide the number of minutes by 60 and add it to the number of hours:

6 hours + (34 minutes / 60) hours = 6 + (34/60) hours = 6.57 hours (rounded to two decimal places)

Now we can calculate Dominic's average speed:

Average Speed = Total Distance ÷ Time

Average Speed = 324 miles ÷ 6.57 hours

Average Speed ≈ 49.35 miles per hour (rounded to two decimal places)

Therefore, Dominic's average speed was approximately 49.35 miles per hour.
