A car starts from rest at 5 . 00 pm . The distances covered by the car at various instants of time are recorded as follows: Time ( pm ) 5 . 00 5 . 30 6 . 00 6 . 30 7 . 00 7 . 30 Distance ( km ) 0 30 60 90 120 150 Draw a distance – time graph.

If an object moves along a straight line, the distance travelled can be represented with the help of a distance-time graph. In the distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient the faster the object will move.

Here the car is travelling equal distance at an equal interval of time. Hence, the car is executing uniform motion. Thus, the speed of the car is a constant. Every 30 minutes, it travels 30 kilometres. Hence at 6 . 15 pm , the distance covered by the car will be 60 + 15 = 75 km .
