1. An object is moving along a straight road at the speed of 6km/h.
a. How further away is the object every one hour?
b. How further away is the object every half (1/2) hr?
c. How further away is the object very 1/3hr? plot (draw) the s against t graph for its motion
a) 6Km because it moves at 6Km/hr
b) 1/2 the distance i.e 6/2 = 3Km
c) 1/3 of 6 Km = 2 Km

To solve these problems, we need to understand the relationship between speed, distance, and time. The formula to calculate distance is:
Distance = Speed × Time
Now let's apply this formula to each part of the question:
a. Every hour, the object is moving at a speed of 6 km/h. So, after one hour, the distance covered would be:
Distance = 6 km/h × 1 h = 6 km
Therefore, the object is 6 km further away every hour.
b. Every half hour, the object covers half the distance it would cover in one hour. So, the distance covered after half an hour would be:
Distance = 6 km/h × 0.5 h = 3 km
Therefore, the object is 3 km further away every half hour.
c. Similarly, let's calculate the distance covered every 1/3 hour:
Distance = 6 km/h × (1/3) h = 2 km
Therefore, the object is 2 km further away every 1/3 hour.
To plot the graph of distance (s) against time (t) for its motion, we can create a table with different values of time and calculate the corresponding distance. Then we can plot these points on a graph to get our line:
Time (h) | Distance (km)
---------------------------
0 | 0
1/3 | 2
2/3 | 4
1 | 6
Once we have these points, we can plot them on a graph with time (t) on the x-axis and distance (s) on the y-axis. Draw a straight line connecting the points, and you will have the graph of the object's motion.
