    Let the distance be x. Time taken by A is T, so time taken by B is T+60 and time taken by C is T+90.
    From statement A, we know that the ratio of speeds of A and C is x:(x-375) = x/T : x/(T+90)
    We have only 1 equation and 2 unknows. We need the second statement to find the values. So, the question can be answered by using both the statements together.
