Sameera was driving a car with uniform speed of 60 kmph. Draw distance-time graph. From the graph find the distance travelled by Sameera in

(i)

(ii) 2 hours

(iii)

Given that, speed = 60 kmph.

Also, distance = speed× time

⇒ d = 60 t (where, d = distance, t = time);

For graph, we’ll first make the table of solutions by putting some random values of x and thereafter we’ll find corresponding values of y and then we’ll plot these points on graph, join them and extend them in straight line to find the graph.

(Note: ∵ equation is linear graph will always be straight line.)

Table of solutions for the given equation-

GRAPH:

(i) Given, t = 1.5 hr.

From the graph, we have corresponding y = 90 km. (pt. E)

(ii) Given, t = 2 hr.

From the graph, we have corresponding y = 120 km. (pt. F)

(iii) Given, t = 3.5 hr.

From the graph, we have corresponding y = 210 km. (pt. G)
