Ketisha is practicing for a marathon by running around a track that is 440 yards long. Yesterday she ran around the track 20 times. How many miles did she run?

If she ran a 440 yd track 20 times, you would multiply the two numbers together. Each lap around the track would be 440 yds, so if she ran 440 yards 20 times (440 * 20), she would have ran 8,800 yards. Convert this to feet to find the distance in miles (one yard is 3 feet, so she ran 8,800*3 = 26,400ft). One mile is 5280 feet, so divide the feet she ran by the number of feet in a mile. The answer is 5. She ran 5 miles.

5

Step-by-step explanation:

It is 5 because we needed to multiply 440 times 20 and we get 8,800.

Then we need to convert it by dividing 26,400 by 5,280 and we get 5.
