Question

How do I find out where two cars intersect when I am given velocity for the red car 14.41cm/s and the starting point for the red car 0.6m. I am also given velocity for the blue car 41.32cm/s and the starting point at 0m.

Answer 1

Explanation:

Write equations for the position of each car as a function of time.  (Make sure to convert units if they're different.)

The red car's position x at time t is:

x = (14.41 cm/s) t + 60 cm

The blue car's position x at time t is:

x = (41.32 cm/s) t

To find when they meet, set the equations equal to each other.

(14.41 cm/s) t + 60 cm = (41.32 cm/s) t

60 cm = (26.91 cm/s) t

t = 2.230 s
