Consider the kinematic equation:

$\overline{)\mathbf{}{\mathbf{\u2206}}{\mathit{x}}{\mathbf{=}}{\mathbf{}}{{\mathit{v}}}_{{\mathbf{0}}}{\mathit{t}}{\mathbf{+}}{\frac{1}{2}}{\mathit{a}}{{\mathit{t}}}^{{\mathbf{2}}}}$

Since the car is travelling at a constant speed, acceleration, a = 0 m/s^{2}

The equation then becomes, Δx = v_{0}t

You can enter units that are combinations of units with prefixes. However, you must maintain the same unit system given in the problem. For example, this question uses the SI unit system. Therefore an answer in U.S. customary units, such as miles per hour would not be accepted as correct.

A car traveling with constant speed travels 150 km in 7200 s. What is the speed of the car? Express the speed with the appropriate units.
