15 kilometers Questions: 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 of 15 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 speed by 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 by 10 kilometers per hour at a distance of 15 kilometers and reaches school at - hours, 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 another 30 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 30 kilometers per hour and he plans to drive in at most 2 hours, how will you write the inequality to find the additional distance?

Question
Transcribed Image Text: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 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.
