Ramesh is driving his car with a uniform speed of 80 km/hr. Draw the time
distance graph. Form the graph find the distance travelled by him in.
(i)1^1/2
(ii) 3 hours

We know that,
Distance (d) = Speed (s)Time (t)
We are given,

At, t = 0 , d = 0
And at t = 1 , d =80
Using above data to plot a graph between d and t,
the graph is as follows-
,

1. 
At, t = 1.5 hours,
d = 120 Km
So, distance travelled in 1.5 hours is 120 km

2.
At, t = 3hours,
d = 240 Km
So, distance travelled in 3 hours is 240 km
