Question

Izzy runs on the schools track team. She runs 4 3/5 miles in 2/3 hour. What is Izzy's speed in miles per hour?

Answer 1

6 9/10 miles per hour

Explanation:

To find what Izzy runs in 1/3 of an hour, divide the miles ran in 2. (converted into decimals 3/5 is 0.6). 4.6/2 = 2.3. Now we can multiply 2.3 by 3 to get how many miles Izzy can run in 1 hour. 2.3 * 3 = 6.9. Converted back into fraction form, Izzy runs 6 9/10 miles per hour.
