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.
Yes that statement is true.

Answer:
x=18
Step-by-step explanation:
The angles here are alternate interior angles, this means that they are congruent. Congruent means that they are equal to each other, so to solve just set them equal! (Your variable is x so you're solving for that)
Divide both sides by 4:
