Aarushi was driving a car with uniform speed of 60 km/h. Draw distance-time graph. From the graph, find the distance travelled by Aarushi in.$2\frac{1}{2}$ hours
Given:
Aarushi was driving a car with uniform speed of 60 km/h.
To do:
We have to draw distance-time graph and find the distance travelled by Aarushi in $2\frac{1}{2}$ hours.
Solution:
Speed of the car $= 60\ km/h$.
We know that,
Speed $=\frac{\text { Distance }}{\text { time }}$
Let the distance be $y$ and time be $x$
Speed $=\frac{y}{x}$
$=60$
$\Rightarrow y=60x$
To represent the above equation graphically we need at least two solutions for the equation.
If $x=0.5$, then $y=60 \times 0.5=30$
If $x=2.5$, then $y=60 \times 2.5=150$
$x$ | $0.5$ | $2.5$ |
$y$ | $30$ | $150$ |
The above situation can be plotted graphically as below:
From the graph,
The distance travelled by Aarushi in $2\frac{1}{2}$ hours is 150 km.
