The speed of a boat in still water in 20 km/hr and the rate of current is 6 km/hr. The distance travelled downstream in 12 minutes is:	Choices:
A) 10.6 B) 5.2 C) 10.8 D) 5.4 E) 5.0
Speed downstream = (20 + 6)= 
<gadget id="calculator">(20 + 6)</gadget>
<output>26</output>
26 kmph   Time= 24 minutes =12/60 hour = 1/5 hour   Distance travelled = Time × speed =1/5×26 = 5.20 km   Answer is 5.2.
