Expert Answer
Distance = speed × Time .
Table below shows the distance travelled at the given time instances
| Time ( hr) | Distance (km) |
| 0 | 0 |
| 1 | 60 |
| 2 | 120 |
| 3 | 180 |
| 4 | 240 |
Distance-Time graph is plotted using EXCEL and it is given below
From graph, we see that at t = 1/2 hour , distance travelled = 30 km
From graph, we see that at t = 2.5 hour , distance travelled = 150 km
