Help maths 10 points

[From: ] [author: ] [Date: 11-05-30] [Hit: ]
when the car is at 30 seconds,=base*height==>10*u.=20u,Hence the time is 30 seconds until the car travels to 2D.......
allright this is not my ****** home work iam serious i have an exam tommorw and id really appreaciate it if you could help me with this question please click on the link http://www.xtremepapers.me/CIE/Cambridge… the question number is 25 if you cannot solve the question or wish to type in something negative to compensate for your lack of knowledge then leave

The area under the graph gives distance travelled, hence area uptill 20 seconds:
0.5*base*height=0.5*20*u==>10*u.
hence D=10u
2D=20u.
when the car is at 30 seconds, the area between 20 and 30 seconds:
=base*height==>10*u.
total distance travelled:
=10u+10u
=20u,
Hence the time is 30 seconds until the car travels to 2D.
