A person covered one-fourth of the total distance at 26 kmph and remaining distance at 24 kmph. What is the average speed for the total distance?
Choose the correct choice from the following answers: A) 21 (1/3)kmph B) 22 (1/3)kmph C) 24 (1/3)kmph D) 26 (1/3)kmph E) 26 (1/3)kmph
21 (1/3)kmph   21 (1/3)kmph   Let the total distance be x km   total time taken = (x/4)/16 + (3x/4)/24 = x/64 + x/32 = 3x/64   21 (1/3)kmphverage speed = x/(3x/64) = 64/3kmph = 21 (1/3)kmph.
