LT 3.1 Flashcard Determine Rate of Change

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

How do you convert miles per hour (mi/h) to kilometers per hour (km/h)?

Back

To convert mi/h to km/h, multiply by 1.60934.

Front

If a car travels 150 miles in 3 hours, what is its speed in miles per hour?

Back

50 mi/h

Front

What is the rate of change in the context of motion?

Back

Rate of change refers to how quickly an object changes its position over time.

Front

How do you calculate the rate of change for a cyclist covering 90 miles in 5 hours?

Back

Rate of change = 90 miles / 5 hours = 18 mi/h.

Front

What is the speed of a boat that travels 120 miles downstream in 3 hours?

Back

40 mi/h

Front

How do you determine the speed of a train that travels 240 miles in 4 hours?

Back

Speed = 240 miles / 4 hours = 60 mi/h.

Front

What is the speed of a runner who completes a 10-mile race in 50 minutes?

Back

To find speed in mi/h, convert 50 minutes to hours (50/60) and then calculate: Speed = 10 miles / (50/60) hours = 12 mi/h.

Front

What is the significance of understanding rate of change in real-world applications?

Back

Understanding rate of change helps in analyzing motion, speed, and efficiency in various contexts.

Front

What units are commonly used to express speed?

Back

Speed is commonly expressed in miles per hour (mi/h) or kilometers per hour (km/h).
