$\dpi{120} \fn_jvn \large \frac{300}{4}=\frac{x}{7}$

$\dpi{120} \fn_jvn \large x=\frac{300\times 7}{4}$

$\dpi{120} \fn_jvn \large x=525km$

hence, the distance covered by the car in 7 hours is 525km.

Usually we see institutes offering objective based learning which usually causes a lag behind in subjective examinations which is the pattern followed by schools. I think it is really a work of planning to make us students grab the advantages of modes of examination, Objective Subjective and Online as well.
