Xiao Ming has two equally long roads from home to school. One is a flat road; the other half is an uphill road and the other half is a downhill road; Xiao Ming takes the same time to go to school on both roads. It is known that the speed of going downhill is (5/4) times that of a flat road, so how many times is the speed of going uphill than a flat road?
