Read each question carefully and show all your work. Round your answers to two decimal places where appropriate. Remember that speed = distance / time.
1. A car travels at an average speed of 80 km/h for the first 2 hours of a journey and then at an average speed of 100 km/h for the remaining 3 hours. Calculate the total distance traveled and the overall average speed for the entire journey.
2. If an object's velocity changes from 10 m/s to 30 m/s in 5 seconds, its acceleration is m/s². This means its speed is increasing by m/s each second.
3. Two trains are 500 km apart and moving towards each other. Train A travels at 70 km/h and Train B travels at 80 km/h. How long will it take for them to meet?
3 hours
3.33 hours
4 hours
4.5 hours
4. If you double the distance traveled in the same amount of time, your speed also doubles.
True
False
5. A boat travels 60 km upstream against a current of 5 km/h in 4 hours. How long will it take the boat to travel the same distance downstream with the current?
