Question

raj was driving car with uniform speed of 60km/h .draw distance time graph .from graph, find distance travelled in (a) 2 and half hours (b) half hour

Answer 1

Distance time graph is attached to a file.
a) Speed= 60km/h   
Time=2 1/2 hr
Distance= Speed *Time
= 60 * 2 1/2
=150 km
Therefore,
Distance travelled in 2 1/2 hr is 150 km.
b) Speed= 60 km/h 
Time= 1/2 hr
Distance= Speed * time 
=60 * 1/2
=30 km
Therefore, distance travelled in 1/2 hr is 30 km.
