Question 1: Calculate the distance traveled when a vehicle moves at a constant speed of 60 km/h for 2 hours.

Answer: 120

Question 2: A car accelerates from 0 to 30 m/s in 10 seconds. Assuming constant acceleration, what is the total distance traveled during this time?

Answer: 150

Question 3: Plot the graph of y = 2x for x values from 0 to 5. Use the grid to draw the line.

Answer: Students draw the line y=2x between points (0,0) and (5,10).

Question 4: A cyclist travels at 15 km/h for 3 hours. What is the distance covered?

Answer: 45

Question 5: A velocity-time graph shows a straight line from (0, 0) to (4, 20). What is the total distance traveled?

Answer: 40

Question 6: Explain the difference in calculating distance when the velocity is variable versus constant, using examples.

Answer: For constant velocity, distance = speed × time. For variable velocity, you need to find the area under the velocity-time graph, which may involve calculating parts of the graph, such as triangles or trapezoids.

Question 7: A train moves at 80 km/h for 1.5 hours, then slows to 40 km/h for the next 2 hours. Find the total distance traveled.

Answer: 220

Question 8: On a velocity-time graph, a straight line from (0, 0) to (5, 10) and then back to (10, 0). What is the distance traveled over the entire period?

Answer: 30

Question 9: Identify and correct the mistake: A student calculates distance by multiplying the velocity at the end of the time period by the total time, assuming constant velocity.

Answer: The mistake is assuming constant velocity at the final speed; for variable velocity, the correct method is to find the area under the graph, not just multiply the final velocity by time.

Question 10: A person walks along a path with a velocity that varies. The velocity-time graph is a triangle with a base of 4 minutes and a height of 3 m/min. Calculate the total distance traveled.

Answer: 6

Question 11: A vehicle's velocity-time graph shows a constant velocity of 50 km/h for 3 hours, then a sudden stop for 0.5 hours, and then a return to 50 km/h for another 2.5 hours. Find the total distance traveled.

Answer: 200
