    Answer:

    1025km

    Explanation:

    T1  = 3hours

    Speed 1 = 115 km/h

    T2  =  5 hours

    Speed 2  = 136 km/h

    Unknown:

    Distance traveled by the fly = ?

    Solution:

    Speed is the rate of change of distance with time.

              Distance  = speed x time

    Now that we know the speed and time, we can calculate the distance covered;

          Distance  = D1 + D2

    D1  = 115 km/h x 3hr = 345km

    D2 = 136km/hr x 5hr = 680km

        Distance  =  345km + 680km  = 1025km
