Reverse transcriptase is the viral enzyme responsible for making a DNA copy of the RNA genome from a retrovirus. As such, it is technically known as an RNA-dependent DNA polymerase. This is opposite to the usual flow of genetic information from DNA to RNA to protein.
This means downhill sections of the ride may be faster, and uphill sections slower. 1  Easy: Under 10 mph. 2  Leisurely: 10-12 mph. 3  Steady: 12-14 mph.  Moderate: 14-16 1  mph. Brisk: 16-18 2  mph. Vigorous: 18- 20 3  mph. Strenuous: 20-22  mph. Super Strenuous: 22+ mph.
Horses, mules, and donkeys (equines) move at a walking pace of about 4-5 miles per hour. A fast trot can be as much as 9 mlp, a gallop 20 or more. However, a gallop cannot be sustained all day, the animal would have to alternate with short bursts of speed and then periods of just walking or trotting.
