The speed-time graph for a car is shown is Fig.
- Find how far does the car travel in the first 4 seconds. Shade the area on the graph that represents the distance travelled by the car during the period.
- Which part of the graph represents uniform motion of the car?
- Find how far does the car travel in the first 4 seconds. Shade the area on the graph that represents the distance travelled by the car during the period.
- Which part of the graph represents uniform motion of the car?
Solution and Explanation
(a)
The shaded area which is equal to \(\frac{1 }{ 2} \times 4 \times 6 = 12 \;m\) represents the distance travelled by the car in the first \(4\) \(s\).
(b)
The part of the graph in red colour between time \(6\) s to \(10\) \(s\) represents uniform motion of the car.

- The text you read is a travelogue where the author, Vikram Seth, talks about his visit to two sacred places in Kathmandu. Imagine that you were with Vikram Seth on his visit to Pashupatinath temple, and you were noting down all that you saw and did there, so that you could write a travelogue later.
Record in point form • what you see when you reach the Pashupatinath temple • what you see happening inside the temple • what you do when inside the temple • what you see outside the temple • what your impressions are about the place.- CBSE Class IX

Concepts Used:
Speed and Velocity
The rate at which an object covers a certain distance is commonly known as speed.
The rate at which an object changes position in a certain direction is called velocity.
