A man's speed with the current is 15 km/hr and the speed of the current is 2.8 km/hr. The man's speed against the current is?  Choose the correct choice from the following answers
A) 9.4  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 2.8 km/hr   Hence, speed of the man = 15 - 2.8= 
<gadget id="calculator">15 - 2.8</gadget>
<output>12.2</output>
12.2 km/hr   man's speed against the current= speed of the man - speed of the current   = 12.2 - 2.8= 
<gadget id="calculator">12.2 - 2.8</gadget>
<output>9.4</output>
9.4 km/hr   9.4nswer is 9.4.
<result>A</result>
A man's speed with the current is 15 km/hr and the speed of the current is 2.8 km/hr. The man's speed against the current is?
