Answer 2

Distance travelled is the total length of the path travelled by the car.

$\longrightarrow\sf{d=100\ m+50\ m}$

$\longrightarrow\sf{\underline{\underline{d=150\ m}}}$

Displacement is the linear separation between initial and final points. Here the car moved 100 m forward and then 50 m backward. Then,

$\longrightarrow\sf{s=100\ m-50\ m}$

$\longrightarrow\sf{\underline{\underline{s=50\ m}}}$
