Two whales are moving in the same direction at 60 kmph and 42 kmph. The faster whale manages to cross the other whale in 14 seconds. Find the length of the faster whale in meters. Choose the correct choice from the following:	A) 110 m	B) 45 m	C) 70 m	D) 120 m	E) 113 m
Relative speed = ( 60 - 42 ) * 5 / 18= 
<gadget id="calculator">( 60 - 42 ) * 5 / 18</gadget>
<output>5</output>
5 mps.   Distance covered in 14 seconds= 14 * 5= 
<gadget id="calculator">14 * 5</gadget>
<output>70</output>
70 m.   The length of the faster whale= 70m.   Answer: 70 m
