There is no scientifically agreed-upon average runner. Opinion varies widely, but most anecdotal evidence suggest that seven and 10 minutes per mile is a decent time for anyone new to running.
The answer for each person differs based on a number of factors, including the runner’s age, gender and fitness level, as well as what distance and pace she is trying to accomplish.
If running at a constant speed of 10 minutes a mile, you can cover the 7.5-mile distance for an hour and 15 minutes.
However, the speed at which a runner covers a mile is often a matter of choice. If he is an average person in good shape and runs only a mile, he may finish in seven minutes. But if he is running a marathon, that speed would often be decreased to nine minutes per mile or more.
