Ответ:
Option a: 11.875 miles per hour
Step-by-step explanation:
We can calculate Colleen's average speed using a rule of three:
She rode a total of 9.5 miles in 0.8 hours, so how much she would rode in 1 hour (this way we can calculate her speed in miles per hour)
9.5 miles -> 0.8 hours
X miles -> 1 hour
9.5/X = 0.8
X = 9.5 / 0.8 = 11.875 miles per hour
The correct option is option "a".
Ответ:
Collen's average speed was 11.875 miles/h
Step-by-step explanation:
The average speed is given by the total distance travelled divided by the time at which the route was completed. So in this case the total distance is 9.5 miles and the time to complete it was 0.8 hour. We then have:
average speed = total distance/ time
average speed = 9.5/0.8 = 11.875 miles/h
Collen's average speed was 11.875 miles/h
