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
