Question

The graph given below shows the distance travelled by a bus in some particular time. The speed of the bus between time = 2 h and time = 4 h is km/h.

• A. 5
• B. 10
• C. 15
• D. 0

Answer 1

The correct option is D 0


$\text{We know, Speed}=\frac{\text{Distance covered}}{\text{Time}}$

From the graph, we observe:
$\text{When time = 2 h, distance covered = 10 km}$
$\text{When time = 4 h, distance covered = 10 km}$

$\text{Speed = Rate of change}=\frac{\text{Change in distance}}{\text{Change in time}}$

$=\frac{10-10}{4-0}=0$

Therefore, speed between time = 2 h and time = 4 h is zero.
