P beats Q by 125 meter in a kilometer race. Find Q's speed if P's speed is 32 meter/sec.
Choose the most appropriate option:	A) 21 meter/sec	B) 7 meter/sec	C) 14 meter/sec	D) 18 meter/sec	E) 28 meter/sec
P's speed = 32 m/s   P's distance = 1000m (as it is a km race)   t = 1000/32= 
<gadget id="calculator">1000/32</gadget>
<output>125/4 = around 31.25</output>
31.25 sec   Q's distance= 1000-125= 
<gadget id="calculator">1000-125</gadget>
<output>875</output>
875m   Q's time to complete this distance is also 62.5 sec.   Q's speed= dist/time = 875/31.25= 
<gadget id="calculator">875/31.25</gadget>
<output>28</output>
28 m/s   Hence 28 meter/sec is the answer.
<result>E</result>
P beats Q by 125 meter in a kilometer race. Find Q's speed if P's speed is 32 meter/sec.
