Total Distance=X miles,Speed =60 miles/hr

Normal time taken=X/60

D1=5 miles S1=30 miles/hr,T1=1/6

D2=x-5 miles S2=60 miles/hr,T2=x-5/60

Total time taken=(1/6)+(x-5)/60


Percentage=([1/6)+(x-5)/60-(x/60)]/[(x/60)] * 100

=500/x

If the slope is positive,the line goes upwards.

So the points can be in first quadrant(a,b) or third quadrant(-a,-b).

The only event referred in the sentence is 'Demystification/Demystifying'.

The Idiom for 'Consider' is:

Consider X Y

Consider(+Nothing)

C is wrong.

Pick D
