    Answer: (1) 2.5 hrs.
    Explanation:-
    Speed of a truck = 90 km/h
    Distance cover by a truck in 3/2 h = 90 x 3/2
    = 45 x 3  = 135 kms
    Total distance = 310 km
    Remaining distance = 310 – 135 = 175 km
    Time taken by a truck which is speed 70 mk/h = 175/70
    = 2.5 hrs.
    Hence, the answer is (1) 2.5 hrs.
