    Answer:

    Step-by-step explanation:

    Solution


    The only technical knowledge we need to know here is the equation


    speed = distance/time


    On the way up the col, therefore 15 = d/t, where d is the distance up and t is the time it takes to get there.

    On the way down, 45 = d/T, where T is the time it takes to get back.


    In other words, d = 15t, and d = 45T. Putting these together, 15t = 45T or t = 3T.


    We also know that t + T = 2. So, 3T + T = 2, which reduces to T= 1/2. The distance from the bottom to the top of the col, d, is 45/2 = 22.5 km.
