    Answer: (1) 3 : 4
    Explanation:-
    Distance covered by car = 200 km
    Time taken by car to covered the distance 200 km = 2 h 40 min
    = 2 + 40/60 = 2 + 2/3
    =8 /3 hr.
    Formula-
     Speed = Total distance / total time taken to the distance.
    Then, the speed of car = 200 x 3/8
    =  25 x 3 = 75 km/hr.
    If time taken by jeep to covered the same distance = 2 h
    Then, speed of jeep = 200/2  = 100 km/hr.
    The ratio of their speed = 75/100
    = 3 : 4
    Hence, the answer is (1) 3 : 4.
