Distance b/w Danton to Griggston?
Statement 1
Danton to Milton = 130miles
Milton to Griggston = 110miles
Danton to Griggston = Danton to Milton + Milton to Griggston = 130miles + 110miles = 240miles
Though, we don't know if this is the shortest path, as Griggston might be in between Danton to Milton
Insufficient
Statement 2
Let the distance from Danton to Griggston = d
Let the time taken to travel from Danton to Griggston = t
Speed = Distance/Time
45 = d/(t-3) => d =45(t-3)
30 = d/t => d = 30t
45(t-3) = 30t
15t = 45*3
t = 9
d = 30t
d = 30*9 = 270miles
Sufficient
Statement 1
Danton to Milton = 130miles
Milton to Griggston = 110miles
Danton to Griggston = Danton to Milton + Milton to Griggston = 130miles + 110miles = 240miles
Though, we don't know if this is the shortest path, as Griggston might be in between Danton to Milton
Insufficient
Statement 2
Let the distance from Danton to Griggston = d
Let the time taken to travel from Danton to Griggston = t
Speed = Distance/Time
45 = d/(t-3) => d =45(t-3)
30 = d/t => d = 30t
45(t-3) = 30t
15t = 45*3
t = 9
d = 30t
d = 30*9 = 270miles

How many miles long is the route from Danton to Griggston?
(1) It is 130 miles from Danton to Milton, which is 110 miles from Griggston.
DM=130, MG=110
we don't know the exact order among D,M,G
so we should consider all possible order
the order could be:
D->M->G or M->G->D, making DG=240
D->G->M or G->M->D, making DG=20
hence, insufficient.
(2) It will take 3 hours less to travel the entire route from Danton to Griggston at an average rate of 45 miles per hour than at an average of 30 miles per hour.
D=45*T=30*(T+3), T=6, D=45*6=270
hence, sufficient.
