[ "A)60 km/h", "B)70 km/h", "C)117.64 km/h", "D)100 km/h" ]
C
Given Speed = 60 Kmph. It means Preeti covered 60 km in 60 min (1 hour). So, in 40 min he will cover 40 km. 50% time reduced = 40 - 50% of 40 = 20 min. Thus, Preeti needs to cover 40 km in 20 min (0.34 hour). Speed * Time = Distance. Speed * 0.34 = 40 Speed = 117.64 kmph. ANSWER : OPTION C
