**drwls**, Saturday, February 4, 2012 at 10:48am1. Xcar = 0.7 t^2

Xbus = 12 t

0.7t^2 = 12t

0.7 t = 12

t = 17.14 seconds

Set Xbus = Xcar and solve for t

2. Use the t from part 1 and

Vcar = 1.4 t

to get the car's velocity.

3. Use the t from part 1 and either of the X equations, to get the distance travelled.
