Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A toy train moves along a straight track 150 m north and then turns back for another 50 m south. Calculate its overall distance and displacement.
Solution: Total distance = 150 m + 50 m = 200 m; Displacement = 150 m - 50 m = 100 m north.
Hint: Use the total of both paths for distance, but only calculate the net for displacement.

💡 Hint: Use the total of both paths for distance, but only calculate the net for displacement.

Challenge 2 Hard

A sprinter runs 400 m in 50 seconds. If she runs back to the start point, calculate the distance and displacement.
Solution: Distance = 400 m + 400 m = 800 m; Displacement = 0 m.
Hint: What happens to displacement when you return to your start point?

💡 Hint: What happens to displacement when you return to your start point?
