Okay. Draw a graph. Just a square wuth 10 lines in it. And then you can do the problem on that. Its really simple. A car Travels for 10 S at a steady speed of 20 M/S along a Street Rd. The traffic lights ahead and change to read in the car shows down with a constant the deceleration, so that if it stops after in a dish and on eight seconds.

Use your graph yo deduce how far the car has traveled during the 18 seconds described.
18x8x20x10x88=
