Read each question carefully and show all your work. Remember the formulas: Speed = Distance/Time, Distance = Speed × Time, Time = Distance/Speed. Pay attention to units.
1. A car travels 240 kilometers in 3 hours. What is its average speed?
60 km/h
80 km/h
720 km/h
120 km/h
2. How far will a cyclist travel in 45 minutes if their average speed is 20 km/h?
9 km
15 km
20 km
26.67 km
3. If a train travels at a constant speed of 100 km/h, it will cover a distance of 350 km in hours.
4. To convert a speed from meters per second (m/s) to kilometers per hour (km/h), you should multiply by .
5. A runner completes a 400-meter race in 50 seconds. Calculate their average speed in m/s. Then, convert this speed to km/h.
6. Explain the difference between average speed and instantaneous speed. Provide an example for each.
7. If an object is accelerating, its instantaneous speed is always changing.
True
False
8. A car traveling at a constant velocity has zero acceleration.
True
False
9. The graph below shows the distance traveled by a remote-controlled car over time. Use the graph to answer the following questions.
a) What is the speed of the car between 0 and 10 seconds?
b) What is the speed of the car between 10 and 20 seconds?
c) Is the car's speed constant throughout the entire journey? Explain your answer.
10. A truck leaves city A and travels towards city B at an average speed of 80 km/h. At the same time, a car leaves city B and travels towards city A at an average speed of 100 km/h. The distance between city A and city B is 450 km. How long will it take for the truck and the car to meet?
