Answer:
20 miles
Explanation:
She traveled 4 miles in 15 minutes.
She went at the same speed for another hour.
1 hour is 60 minutes.
60 = 4 * 15
There are 4 15-minute periods in an hour.
Since she went 4 miles in 15 minutes, she went 4 * 4 miles in 1 hour.
4 * 4 miles = 16 miles.
She went 4 miles in 15 minutes and another 16 miles in an hour.
The total distance she traveled is 4 miles + 16 miles = 20 miles.
Answer: 20 miles
