Answer : 1. "48 kmph"
Explanation :
Answer: A) 48 kmph Explanation: Let the initial speed of Akhil be '4p' kmph Then speed after decrease in speed = '3p' kmph We know that, Change in speed == Change in time According to the given data, 243p - 244p = 35 - 2560=> p = 12 Hence, the initial speed of Akhil = 4p = 4 x 12 = 48 kmph.
