Question

The given figure shows the distance-time graph of three cars $A$, $B$ and $C$. Study the graph and answer the following question:


Which of the three is the fastest?

• A. $A$
• B. $B$
• C. $C$
• D. $A$ and $C$ have same speed

Answer 1

The correct option is B $B$

$Speed=\frac{Distancetravelled}{Timetaken}$
= Slope of distance-time graph

Since the slope of distance-time graph for car $B$ is the largest, it is travelling at the maximum speed. Hence, car $B$ is the fastest.
