A boat running downstream covers a distance of 10km in 3hr while for covering the same distance upstream, it takes 6hr.
What is the speed of the boat? Choose the correct choice from the following answers:
A) 2.5 kmph
B) 3.5 kmph
C) 4.5 kmph
D) 1.5 kmph
E) 9.5 kmph
speed upstream = 10/3   speed of boat down stream = 10/6   speed of boat = 1/2(10/3 + 10 /6 ) = 2.5 kmph   2.5 kmphNSWER:2.5 kmph
