# Mrs. Colen took a trip. She drove 350 miles in 7 hours and 30 minuets. what is her average speed to the nearest tenth of a mile per hour

diatance travelled by her= 350 miles amount of time taken by her to travel 350 miles= 7 hrs 30 mins =450 mins average speed travelled by her to the nearest tenth of a mile per hour= 450*60/100 =270/10 =27 therefore he travelled 27 miles to the nearest tenth of a mile per hour.

7 hours and 30 minutes is 7.5 hours. Average speed can be found by taking distance and dividing it by time. 350 miles/7.5 hours=46.6666 miles per hour. Rounded to the nearest 10th that is 46.7 mi/hr
