Question

The motion of a car along a straight path is shown by the following figure.
The car starts from $O$ and reaches at $A$, $B$ and $C$ at different instants of time. During its motion from $O$ to $C$ and back to $B$, the distance covered and the magnitude of the displacement are respectively

• A. $25km$ and $60km$
• B. $95km$ and $35km$
• C. $60km$ and $25km$
• D. $85km$ and $35km$

Answer 1

The correct option is D $85km$ and $35km$

Distance covered by the car=OA+AB+BC+CD=OA+AB+BC+CD
=25+10+25+25=85=25+10+25+25=85Km
Displacement by the car=OB=35=OB=35Km.
