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.
Answer:
16 miles/hour
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
