For 2 weeks.
In a week there are 7 days.
So for 2 weeks there are a total of 2*7 = 14 days.
So there would be 14 mornings
And if each morning he runs 50 minutes,
So for the 14 mornings = 14 * 50 = 700 minutes
700 minutes converting to hours = 700 / 60 = 11 hours remainder of 40 minutes
So total time = 11 hours and 40 minutes
