In traveling a distance of 2.2 km between points A and D, a car is driven at 106 km/h from A to B for t seconds and 63 km/h from C to D also for t seconds. If the brakes are applied for 4.9 seconds between B and C to give the car a uniform deceleration, calculate t and the distances between A and B. Answers: t= 106 km/h S= i B 2.2 km 63 km/h S km

Mario rides his motorcycle in going to school. He drives at an average speed of 30 kilometers per hour. The distance between his house and the school is 15 kilometers. Every time he sees his best friend Jessica walking on the road, he invites her for a ride and lowers his speed. On the other hand, he increases his speed when he wakes up late for school. a) If x represents the time it takes Mario to drive to school with the given distance of 15 kilometers, how will you represent the relationship of his speed (y) versus the time (x)?
