A car is moving along a straight road at a steady speed. It travels 150 m in 5 seconds. How long does it take to travel 240 m ?
Distance travelled$=150\ m$
Time $=5\ sec$
Therefore, speed of the car $=\frac{150\ m}{5\ sec.}$
$=30\ m/s$
Therefore, time taken to travel $240\ m$
$=\frac{distance}{speed}$
$=\frac{240}{30}$
$=80\ sec.$
