Step-by-step explanation:
Flipping a tails and rolling at least a tail are 2 independent events: they don't affect each other. So, to get the probability of both happening, we just need to multiply the probability of one by the probability of the other. he probability of rolling at least a 2 is 5/6.

V = s/t
now, t is equal for both cases so we write these 2 equations:
440/(Vp+Vw) = t
and
340/(Vp-Vw) = t
Now again, since t is equal for both cases we can make these 2 equations equal to eachother.
440/(Vp+25) = 340/(Vp-25)
(Vp - 25)*44=34*(Vp+25)
44Vp - 1100 = 34Vp + 850
10Vp = 1950
Vp = 195
Answer is 195mph
