Question

Jose was driving to New York City. He traveled 100 miles in the first hour of the trip and 20 miles in the last hour of his trip. Which can we

say about Jose's drive? (speed = distance = time)
A. Jose drove less than 120 miles.
B. Jose drove faster the first hour of his drive.
C. Jose drove slower the first hour of his drive.
D. Jose drove the same speed for the entire drive.

Answer 1

Jose drove 100 miles in the first hour and 20 miles in the last hour; therefore, he drove faster during the first hour of his trip.

Step-by-step explanation:

The question addresses the concepts of speed, distance, and time, which are fundamental in kinematics, a branch of physics often applied in mathematics problems. From the information provided, we know that Jose traveled 100 miles in the first hour and 20 miles in the last hour of his trip to New York City. This data indicates different speeds for each part of the trip. Therefore, we can answer the student's question:

• Jose drove faster the first hour of his drive.

Indeed, covering 100 miles in one hour requires a higher speed than covering 20 miles in one hour. Thus, option B is correct. This conclusion is based on the definition of speed as the distance traveled divided by the time taken to travel that distance. Since we know the distances traveled and the corresponding times, we can compare the speeds for different hours of his trip.

Answer 2

b

Step-by-step explanation:

he drove 5x faster than the time was when he was on the last hour (maybe caught in traffic or wasn't in a rush)
