amara rode her bicycle 8 miles in 0.5 hours.what was the average rate that she rode her bicycle in miles per hour?

8 / 0.5 = x / 1

Cross multiply and solve for x.

Colleen rode her bicycle 9.5 miles in 0.8 hour. What was her average speed in miles per hour?

To calculate the average rate at which Amara rode her bicycle, we need to divide the total distance she traveled by the time it took her.

In this case, Amara rode her bicycle for 8 miles in 0.5 hours. The formula to calculate average rate is:

Average Rate = Total Distance ÷ Time

Plugging in the values:

Average Rate = 8 miles ÷ 0.5 hours

To evaluate this, we can use long division:

8 ÷ 0.5 = 16

Therefore, Amara's average rate of riding her bicycle was 16 miles per hour.
