Concept: 2 Marks
Graph: 2 Marks

Speed of car = 30 km/h

Distance covered in 1 hour $=1\times 30=30km$

Table for distance-time is given below:

$\begin{array}{ccccc}Time& 1& 2& 3& 4\\ Distance& 30& 60& 90& 120\end{array}$

Graph for distance-time is given below:



From graph, Parul takes 4 hours to cover 120 km
