I would guess about 20 minutes.
1.3 miles is 2253.0816 meters. An average step is about 2/3 of a meter, so 2253.0816 / (2/3) = 3,380 This is just an approximation, though, as everyone has a different stride length. An easy way to find your own is lay out a tape measurer and find your own stride length. Then do 2253.0816 divided by your stride length in meters.
The answer depends on the length of your stride.
76 miles per stride.
If the average stride length of an adult female is 2 feet, and that of a male is 2.5 feet (unverified accuracy, but seen elsewhere, and seems about right -- I'm a female and my stride length was just measured yesterday at 2"2'), then a female adult would walk 10,000 feet in 5,000 steps. That's 1.9 miles. For a male adult, at 2.5 feet, it would equal 2.4 miles. Each individual can measure their own stride length and then multiply that number times 5,000 then convert feet to miles. One foot equals 0.000189393939393939 miles. # miles=stride length in feet X 5000 step X 0.000189393939393939
A stride is not a uniform unit of measurement - different people have different stride lengths. The two units are therefore incompatible.
Near 10,000 but it depends on how big your stride is.
A fifty year old should be around the peak of his life - enough fitness to ensure good performance, and aided by maturity in experience. 6km per hour should be well within reach for extended periods.

It all depends on your speed age and level of fitness The average human walks at 3mph, 25 miles /3 mph = 8.33 hours
The average stride pattern for an adult is 2.25ft, so in all you would cover 2,250,000 ft. There are 5280 feet in a mile, therefore on average an adult will cover 426.1 miles in a million steps.
Measure your stride. 3 miles in 45 minutes is 4 miles per hour, which is 5.87 feet per second. If your stride is 2 feet long, you'll have to take close to three strides per second to achieve that rate.
A person of average fitness should be able to cover six miles in one hour. I'm not particularly fit - yet I can walk from my home to the next town (about 3 miles away) in under 45 minutes !
