Answer:
80kmph
Step-by-step explanation:
Given Speed = 60 Kmph.
It means Samarth covered 60 km in 60 min (1 hour). So, in 40 min he will cover 40 km.
25% time reduced = 40 - 25% of 40 = 30 min.
Thus, Samarth needs to cover 40 km in 30 min (0.5 hour).
Speed * Time = Distance.
Speed * 0.5 = 40
Speed = 80 kmph.
