Question
Four cars A, B, C, and D are moving on a levelled road. Their distance versus time graphs are shown in Fig. 8.2. Choose the correct statement.
Options
Car A is faster than car D.
Car B is the slowest.
Car D is faster than car C.
Car C is the slowest

Solution
Car B is the slowest.
As speed, v = `("S"_2 - "S"_1)/("t"_2 - "t"_1)`
For the same time interval (t2 − t1), the distance travelled by cars A, B, C, and D are in the order SC > SD > SA > SB
∴ Car C is the fastest and car B is the slowest.
