Question

Aarushi was driving a car with uniform speed of 60 km/h. Draw distance-time graph. From
the graph, find the distance travelled by Aarushi in

 (1)  ` 2 1/2`  Hours      (2) ` 1/2 ` Hour

Answer 1

Let x be the time and y be the distance travelled by Aarushi
It is given that speed of car is 60/ kmh

We know that speed  = `"distance "/"speed "`

⇒   `60 = y / x` 

⇒ `y = 60x`

Putting   x = 1 , we get y = 60

 Putting  x = 2 , we get y = 120

Thus, we have the following table for the points on the line   y = 60x

x	1	2
y	60	120
