Julia ride her horse 12 miles in 45 minutes. What is her average speed in mil/hour?

16 miles/hour

Step-by-step explanation:

We need to convert minutes to hours. 1 hours = 60 minutes

45 minutes * 1 hour/60 minutes = 45/60 hours = 3/4 hours =.75 hours

12 miles/45 minutes = 12 miles /.75 hours = 16 miles/hour

Answer

16miles/h

Step-by-step explanation:

45minutes is 3/4 of an hour (60 minutes) so multiply 12 and 3/4 (75%) to get 4miles. 4 miles is only 1/4 of her hour so just multiply 4 by 4 to get 16miles.
