10. Complete Activity 7.10 (Page 81).
Feroz and his sister Sania go to school on their bicycles. Both of them start at the same time from their home but take different times to reach the school although they follow the same route. Table 7.5 shows the distance travelled by them in different times
| Table 7.5: Distance covered by Feroz and Sania at different times on their bicycles | ||
| Time | Distance travelled by Feroz (km) | Distance travelled by Sania (km) |
| 8.00 am | 0 | 0 |
| 8.05 am | 1.0 | 0.8 |
| 8.10 am | 1.9 | 1.6 |
| 8.15 am | 2.8 | 2.3 |
| 8:20 am | 3.6 | 3.0 |
| 8:25 am | – | 3.6 |
Plot the distance-time graph for their motions on the same scale and interpret.
Answer:
The graph is plotted below:
We can see that throughout the journey the speed of Sania was less than that of Feroz.
