A brisk walk is about 3 miles an hour, which is faster than a stroll. To get any real health benefits you need to walk over 3 mph for 20 minutes or longer in one stretch. While walking slower or in short bursts has some benefit, you need to get your heart rate up (and burn more calories) for a real cardio benefit.
A distance of 2 miles should take around 30 minutes. 1 mile will take around 14 minutes, while 0.8 miles will take around 11 minutes.
As a general rule, the faster you go, the more calories you will burn exponentially since your body uses more energy to go faster. At a moderate speed per hour you will burn less calories than walking at a faster rate, e.g. a moderate to fast pace.
Several studies have found shown high-intensity training (HIIT) significantly reduces total abdominal fat, including visceral belly fat more effectively than lower-intensity exercise like walking.
2 miles should take about 27 minutes on average.
