Speed Me Up!Read and analyze each situation below and answer the questions that follow.Mario rides his motorcycle in going to school. He drives at an average speed of 30kilometers 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 aride and lowers his speed. On the other hand, he increases his speed when he wakesup late for school. 15 kilometersQuestions:a. How long does it take Mario to reach school considering his average speed?b. If x represents the time it takes Mario to drive to school with the given distance of15 kilometers, how will you represent the relationship of his speed (y) versus the time(x)?c. Mario's average speed as 30 kilometers per hour. Suppose Mario lowers his speedby 10 kilometers per hour, how long will he reach the school given the same distance?d. Suppose Mario's speed is unknown and represented by (x), he lowers his speed by10 kilometers per hour at a distance of 15 kilometers and reaches school at3hours,4-how will you write the equation to find his average speed (x)?e. Mario's average speed was 30 kilometers per hour. He plans to drive for another30 kilometers from school, how long will it take him to cover the whole distance(house to school to 30 kilometers from school)?f. If Mario drives another (x) kilometers from his school at an average speed of 30kilometers per hour and he plans to drive in at most 2 hours, how will you write theinequality to find the additional distance?

How far does the police car travel before reaching its full speed (in ft)? b. How far does the car travel while the police car is speeding up (in ft)? c. How far does the police car travel before catching up with the car (in ft)?

A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average speed, vavg, during this period, in meters per second? 2. What was the motorcycle's displacement in the northern direction during this period, in meters?
Problem-Solving Technique: Draw a labeled picture. Put a coordinate system on the picture indicating the location of the origin and the positive direction. Show the solution in a step-by-step orderly fashion. Write any equation you use in symbolic form before substituting in numbers. 1.

Caravan Analogy.Consider a highway that has tollbooths every 120 km. Suppose that cars travel at a rate of 120 km/hr (cars have instant acceleration to 120 km/hr and maintain that constant speed between tollbooths). If there is a convoy of 22 cars, and it takes each car an average of 24 seconds to clear the tollbooth, calculate the following. a. Suppose the caravan travels 360 km, beginning in front of one tollbooth, passing through a second and third tollbooth and finishing just after a fourth tollbooth. What is the end-to-end delay, in minutes, from the time the first car goes through tollbooth 1 until the last cargoes through tollbooth 4? b.The cast members of “The Fast and the Furious” show up. Instead of 22 cars, there arenow 18 cars. These 18 cars travel 220 km/hr instead of 120 km/hr. What is the new end-to-end delay in minutes? c. Consider the diagram below. The police are on to the cast of “The Fast and the Furious”. These 18 cars travel 280 km/hr on segments A and B (where…
