Two cars are 150km away from each other and they are going to the same(direction,vector,....).The first car is going 70km/h and the second car is going 20km/h. After x-hours the first car would catch the second car and they would be at the same point. Find x=?

Isn't this the sort of math problem we solve in 7th grade?
x1 = 0 + 70*t
x2 = 150 + 20*t
x1 = x2 <=> 70t = 150 + 20t
50t = 150
t = 3 hours
x1 = 70 * 3 = 210km
x2 = 150 + 2*3 = 150 + 60 = 210km

7th grade, seriously? Looks like I'm gonna have to start saving now for tutors for my kid.
Judging from that it'll be from grade 4-12.
That's if she makes it that far with half my genes. :-)

Here's another maths question:
A linguistically, grammatically challenged mathematicient [sic] at twice the speed of sound (as measured through diesel oil) approaches an atheist message board. Negating air resistance, how long will it take him to explain how arithmetic problems 'beat religion'?
Solve for x.
