A man's speed with the current is 15 km/hr and the speed of the current is 3.2 km/hr. The man's speed against the current is? Choose the correct choice from the following options
A) 10 B) 20 C) 50 D) 8.6 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 3.2 km/hr   Hence, speed of the man = 15 - 3.2=

<output>11.8</output>
11.8 km/hr   man's speed against the current= speed of the man - speed of the current   = 11.8 - 3.2= 
<gadget id="calculator">11.8 - 3.2</gadget>
<output>8.6</output>
8.6 km/hr   Answer is 8.6.
<result>D</result>
