Problem
Two cars start to move from the same point at the same time with velocities v1=100km⋅h−1
and v2=60km⋅h−1. Is it possible for the cars to move away from each other at any of the
following velocities? If so, sketch the situations.
\begin{alignat*}{2}
v_a &= 160\,\mathrm{km\cdot h^{-1}} \,, & v_b &= 40\,\mathrm{km\cdot h^{-1}} \,,
v_c &= 30\,\mathrm{km\cdot h^{-1}} \,, & v_d &= 90\,\mathrm{km\cdot h^{-1}}
\end{alignat*}
