Choose one
A) 8 hours 12 minutes	B) 6 hours 15 minutes	C) 7 hours 20 minutes	D) 7 hours 12 minutes	E) None
Explanation :   Let the time taken by car A to reach destination is T hours   So, the time taken by car B to reach destination is (T – 2) hours.   S1T1 = S2T2   =&gt; 40(T) = 55 (T – 2)   =&gt; 40T = 55T -110   =&gt; 15T = 110   T = 7 hours 20 minutes   Answer – 7 hours 20 minutes
