1-9 A traffic police officer observes a fast moving car. Due to over speed officer starts his bike, accelerates uniformly to \( 90 kph \) in \( 8 s \), and maintaining a constant velocity of \( 90 kph \), overtakes the car \( 42 s \) after the car passed him. If he overtakes the car after \( 18 s \) from the instant he starts, find the distance the officer travelled before overtaking and the speed of car.
