Draw the line graph for the following data Time (in hours) 5 10 15 20 Distance travelled by bike (in km) 200 400 600 800

Given: Time (in hours) 5 10 15 20 Distance travelled by bike (in km) 200 400 600 800 We take the time taken to travel (in hrs) on X-axis with a scale of 2 cm = 5 hour s We take distance travelled on Y-axis with a scale 2 cm = 200 kms . From the given data, it takes 5 hrs to travel 200 kms Hence, we need to plot ( 5 , 200 ) on the graph. To plot ( 5 , 200 ) we locate 5 on X-axis and 200 on Y-axis. A point of intersection of vertical perpendicular drawn on 5 of X-axis and horizontal perpendicular drawn on 200 of Y-axis is ( 5 , 200 ) . Similarly, we plot remaining data. We draw segments joining consecutive plotted points. They form one line. Therefore, the graph is linear.

Temperature at different intervals of time of a liquid was observed as shown in the table below. Time ( in min ) 0 4 8 12 16 18 20 Temp in ° C 10 30 50 70 90 100 100 Draw a temperature-time graph. Use that graph to answer the following questions. What is the temperature of the liquid at 10 minutes?

Time ( in min ) 0 4 8 12 16 18 20 Temp in ° C 10 30 50 70 90 100 100 To find the temperature of the liquid at 10 minutes. Temperature-time graph as shown below, We observed that, the temperature at 10 minutes is 60 ° C .

Time ( in min ) 0 4 8 12 16 18 20 Temp in ° C 10 30 50 70 90 100 100 To find the temperature of the liquid at 10 minutes. Temperature-time graph as shown below, From 30 ° C on y - axis draw a line parallel to the x - axis which intersects the line at a point and draw perpendicular line from that point to x - axis. Now mark the point on x - axis where the perpendicular line intersects. We observed that the point where the line and x-axis intersects is 10 Therefore, after 10 minutes the temperature is 30 ° C .

Time ( in min ) 0 4 8 12 16 18 20 Temp in ° C 10 30 50 70 90 100 100 To find the temperature of the liquid at 10 minutes. Temperature-time graph as shown below, We observed that, temperature from 0 minutes to 18 minutes is increasing rapidly. The temperature at 18 minutes and 20 minutes is same and constant. Hence, after 18 minutes the temperature remains constant.
