I guess you mean he had some speed S at 7.5 min and forgot to type it
Did he start at zero speed at 0 time and accelerate constantly?
if so then
v = a t
at 7.5
S = 7.5 a
so a = S/7.5
at time t, v = .25
so
.25 = a t
or
.25= (S/7.5) t
so
t = 7.5 * .25 / S
that will be in minutes of course, multiply by 60 for seconds

Well I have no idea what sort of velocity versus time curve Dan is following.
