comment Which of these arguments is wrong?
@servabat, If Problem statement says: $x^2<x$, what is the solution? what values $x$ can assume?

comment Which of these arguments is wrong?
@servabat, $x < 1 \implies $ any number less than 1 will satisfy OR is a solution for $x^2 < x$ which is not true in case the number is negative

comment Solving speed problem
at time $t_0$ the front of the car is level with the back of the caravan; at time $t_1$ the back of the car is level with the front of the 4WD; from $t_0$ to $t_1$ the car has to travel $(13 + 5)$ m and considering the caravan to be stationary for calculation purpose then the car is travelling at a speed of $(100-64)$ km/h, now we know the speed of the car and the distance it has to travel.

comment Some help with sin and cos
For first part $a=\sin^2\pi/2$, $b=\cos^2\pi/2$ ; $\Large\frac{1-\frac{a}{b}}{1+\frac{a}{b}}=\frac{\frac{b-a}{b}}{\frac{b+a}{b}}= \frac{b-a}{b+a}$ use $\sin^2\theta+\cos^2\theta=1$
