Two cars P and Q start from a point at the same time in a straight line and their positions are represented by xP(t) = (at + bt2) and xQ(t) = (ft $-$ t2). At what time do the cars have the same velocity ?

Question

Two cars P and Q start from a point at the same time in a straight line and their positions are represented by
x_P(t) = (at + bt²) and x_Q(t) = (ft $-$ t²).

At what time do the cars have the same velocity ?

${{a - f} \over {1 + b}}$

${{a + f} \over {2\left( {b - 1} \right)}}$

${{a + f} \over {2\left( {1 + b} \right)}}$

${{f - a} \over {2\left( {1 + b} \right)}}$
