Question 1.
\nA bus runs constantly at a speed of 60 km\/hr. Draw a time-distance graph for the situation. Also find the<\/p>\n

    \n
  1. Time taken to cover 360 km.<\/li>\n
  2. Distance covered in 4\\(\\frac{1}{2}\\) hours.<\/li>\n<\/ol>\n

    Solution:
    \nGiven the bus runs constantly at a speed of 60 km\/hr.
    \ni.e. for 1 hour = 60 km
    \n2 hours = 2 x 60 = 120 km
    \n3 hours = 3 x 60 = 180 km
    \nWe can tabulate as below,
    \n\"Samacheer
    \nTake a suitable scale:<\/p>\n

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

        Question 2.
        \nA company dealing with finance gives 15% simple interest on deposits made by senior citizens. Illustrate by a graph the relation between the deposit and the interest gained. Use the graph to complete the following.<\/p>\n

          \n
        1. The annual interest obtainable for investment of \u20b9 450<\/li>\n
        2. The amount a senior citizen has to invest to get an annual simple interest of \u20b9 100.<\/li>\n<\/ol>\n

          Solution:
          \nUsing the formula for calculating the simple interest, the following table of values is prepared.

          \n\"Samacheer
          \nThese are the points to be plotted in the graph sheet, let us take the deposits along x – axis and annual simple interest along y – axis.
          \nWe choose the scale as follows.
          \nThen we plot the points and draw the straight line.
          \nFrom the graph we find.<\/p>\n

            \n
          1. Corresponding to \u20b9 450 on the x – axis, we get the interest as \u20b9 67.5 on the y – axis.<\/li>\n
          2. Corresponding to \u20b9 100 on the y – axis we get the deposit as \u20b9 666 on the x – axis.<\/li>\n<\/ol>\n

            Question 3.
            \nThe following table gives the quantity of petrol and its cost
            \n\"Samacheer
            \nPlot the graph.
            \nSolution:<\/p>\n

              \n
            1. Take a suitable scale on both the axes. Here we take on the x – axis
              \n1 cm = 1 litre, on the y axis 1 cm = 70 rupees.<\/li>\n
            2. Mark number of litres of petrol along the x – axis<\/li>\n
            3. Mark the cost of petrol along the y – axis.<\/li>\n
            4. Plot the points (1, 70), (2, 140), (3, 210), (4, 280), (5, 350), (6, 420) and (7,490)<\/li>\n
            5. Join the points.<\/li>\n<\/ol>\n

              The graph can help us to estimate few more things also.
