If a car travels 120 miles in 2 hours, what is its average speed?

• A. 50 miles per hour
• B. 60 miles per hour
• C. 70 miles per hour
• D. 80 miles per hour

Answer: (B)

To find the average speed of the car, you can use the formula for average speed, which is the total distance traveled divided by the total time taken. In this case, the car travels 120 miles in 2 hours. First, you calculate the average speed: \[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \] Substituting the given values: \[ \text{Average Speed} = \frac{120 \text{ miles}}{2 \text{ hours}} = 60 \text{ miles per hour} \] Thus, the average speed of the car is 60 miles per hour. This calculation shows how average speed is derived directly from the relationship between distance and time, emphasizing the importance of understanding these basic concepts in mathematics related to motion.

To find the average speed of the car, you can use the formula for average speed, which is the total distance traveled divided by the total time taken. In this case, the car travels 120 miles in 2 hours.

First, you calculate the average speed:

[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} ]

Substituting the given values:

[ \text{Average Speed} = \frac{120 \text{ miles}}{2 \text{ hours}} = 60 \text{ miles per hour} ]

Thus, the average speed of the car is 60 miles per hour. This calculation shows how average speed is derived directly from the relationship between distance and time, emphasizing the importance of understanding these basic concepts in mathematics related to motion.
