Walking over 3 miles an hour is classed as moderate exercise. 2.5 hours every week, so most experts suggest 30 minutes a day, five days a week or if you prefer, 20 minutes every day. If you can manage 4.5 miles per hour or uphill, thats vigorous exercise similar to light running or cycling. At this intensity, an hour and fifteen minutes a week is sufficient.

A distance of 2 miles should take around 30 minutes. 1 mile will take around 18 minutes, while 0.8 miles will take around 14 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 34 minutes on average.
