A man’s speed with the current is 16 km/hr and the speed of the current is 2.5 km/hr. the man’s speed against the current is : Choices.
A) 8.5 km/hr
B) 9.5 km/hr
C) 11 km/hr
D) 12.5 km/hr
E) None of these
Solution   Man's rate in still water = (16-2.5) km/hr = 13.5 km/hr.   Man's rate against the current = (13.5-2.5) km/hr = 11 km/hr Answer 11 km/hr
<result>C</result>
A man’s speed with the current is 16 km/hr and the speed of the current is 2.5 km/hr. the man’s speed against the current is :
