A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is?
Choose the correct choice from the following answers.
A) 10	B) 20	C) 50	D) 30	E) 40
Man's speed with the current = 15 km/hr   =&gt; speed of the man + speed of the current = 15 km/hr   speed of the current is 2.5 km/hr   Hence, speed of the man = 15 - 2.5= 
<gadget id="calculator">15 - 2.5</gadget>
<output>12.5</output>
12.5 km/hr   man's speed against the current= speed of the man - speed of the current   = 12.5 - 2.5= 
<gadget id="calculator">12.5 - 2.5</gadget>
<output>10</output>
10 km/hr   10nswer is 10.
<result>A</result>
