In a flight of 600 miles, an aircraft was slowed down due to bad weather. As a result, the average speed for the trip reduced by 200 miles/hr and the time of flight increased by 30 minutes. The duration of the flight is:
A.1 hour
B.2 hours
C.3 hours
D.4 hours
E. 1.5hours
Or,\(\frac{ 600s - 600s+120000}{s(s-200)} =\frac{1}{2}\)
Or,\( 240000 =s(s-200)\)
Or,\( s =600\)
So, total duration of the original flight was 600/600 = 1 Hour.... Answer must be (A)
...
