Answer:
1/2 hour or 30 minutes (same answer)
Explanation:
If you walk with a constant speed of 4 miles per hour it means that you will walk 4 miles in one hour, therefore if we want to walk 2 miles at the same constant speed it will just be half of the time that the person took before to walk 4 miles, which it was one hour so 2 miles will be 30 minutes.
Someone walks at a constant speed of 4 miles per hour how much time will it take them to walk 2 miles?
At 4 miles an hour, they will walk 4 miles in 60 minutes.
in 30 minutes, they will walk 2 miles.
