Question

A bus runs constantly at a speed of 60 km/hr. Draw a time-distance graph for the situation. Also find the

1. Time taken to cover 360 km.
2. Distance covered in 4 1/2 hours.

Answer 1

Given the bus runs constantly at a speed of 60 km/hr.

i.e. for 1 hour = 60 km

2 hours = 2 x 60 = 120 km

3 hours = 3 x 60 = 180 km

We can tabulate as below,

Hour	1	2	3	4	5	6
Distance	60	120	180	240	300	360

Take a suitable scale:

1. Mark the number of hours on the x – axis
2. Mark the distance in km on the y – axis
3. Plot the points (1, 60), (2,120), (3, 180), (4, 240) and (5, 300)
4. Join the points and get a straight line from the graph.
   • Time taken to cover 360 km is 6 hours.
   • Distance covered in 4 1/2 hours is
