Question

Draw the graphs for the following tables of values, with suitable scales on the axes.

(a) Distance travelled by a car

| Time (in hours) | 6 a.m | 7 a.m | 8 a.m | 9 a.m |
| Distance (in km) | 40 | 80 | 120 | 160 |

(i) How much distance did the car cover during the ** 7.30 a.m. to 8 a.m.?

(ii) What was the time when the car had covered a distance of 100 km since its start?

Answer 1

(a) Taking a suitable scale (for x-axis, 2 units = 1 hour and for y-axis, 2 units = 40 km), we can represent the time on x-axis and the distance covered by the car on y-axis. A graph of the given data is as follows.

(i) During the ** 7:30 a.m. to 8 a.m., the car covered a distance of 20 km.

(ii) The car covered a distance of 100 km at 7:30 a.m. since its start.
