You simply try put the whole example in an equation form.
vc= velocity of car
vp= velocity of the plane
know it is given that the time of both travels is the same, and using the famous velocity time equation you can say,
t=(distance by the car/vc)=(distance by the plane/vp)
so
(150/vc)=(600/vp)
Now, given that vp=150+vc
We have;
(150/vc)=(600/150+vc)
multiply and you get an equality of
150(150+vc)=600vc
150^2+150vc=600vc
make all vc at one side, you have;
150^2=600vc-150vc
then; vc=150^2/450=50
and use the vp=150+vc equation again and you get,
vc=200mph.
Hope this helps.

to calculate percent increase use
× 100%
increase = $650 - $525 = $125
percent increase = × 100% = 24% → B
