A wasp and a ladybug are flying towards each other as shown in the picture. At the moment you first observe the insects (the moment pictured, t = 0), the wasp is at x = 0 and the ladybug at x = 7 m. The wasp travels with a constant velocity of VW= +4 m/s and the ladybug has a velocity that varies with time according to VLB = -6t m/s, where t is the time measured in seconds. At what position will the two insects meet?
