They are driving in opposite directions, so the velocities need to be added together.
65+85=150

Let us take a number x
The four consecutive numbers will be
x+1, x+2, x+3
Thus our equation will be
x + x+1 + x+2 + x+3 = 42
4x + 6 = 42
4x = 36
x= 36/4
x= 9
Thus the four numbers are (substitute)
x=9
x+1=9+1=10
x+2=9+2=11
x+3=9+3=12
9,10,11,12
2t^2 =4t+3t=5t
5t+500
3t^2=9t+t=10t
10t+300
