You would have to do 24.85 x 4 because the 24.85 is per hour and if someone is going for 4 hours, this is what we would have to work out. So it would equal: 99.40 miles per hour. :)

the equation you're using is D=RT
(24.85)=r(4)
24.85=4r   (divide the 4 to get r alone)
r=6.2125
your answer is 6.2125
