A car is moving along a straight road at a steady speed. It travels $150\ m$ in $5\ seconds$ :
(a) What is its average speed ?
(b) How far does it travel in $1\ second$ ?
(c) How far does it travel in $6\ seconds$ ?
(d) How long does it take to travel $240\ m$ ?

As given, a car is moving along a straight road at a steady speed. It travels $150\ m$ in $5\ seconds$.

(a) Distance traveled $=150\ m$

Time $=5\ s$

Therefore, average speed $=\frac{total\ distance}{time}$

$=\frac{150\ m}{5\ s}$

$=30\ m/s$

(b) Distance traveled in $1\ second=averaeg\ speed\times time=30\ m/s\times1\ s=30\ m$

(c) Distance traveled in $6\ seconds=speed\times time=30\ m/s\times 6\ s=180\ m$

(d) As known, $time=\frac{distance}{speed}$

$=\frac{240\ m}{30\ m/s}$

$=8\ s$
