Suppose m is the line with equation y = −4 and ΔA'B'C is mapped to ΔA"B"C" by applying the glide reflection T⟨3, 0⟩ ∘ Rm. What are the coordinates of ΔA″B″C″?
A. A″(−1, −3), B″(−2, −6), C″(1, −7)
B. A″(−7, −3), B″(−8, −6), C″(−5, −7)
C. A″(−2, −5), B″(0, −2), C″(−3, −1)
D. A″(−8, −3), B″(−6, 4), C″(−9, 0)

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
