A runner travels 120 m north, then 50 m south. Calculate the total distance travelled.
120 + 50 = 170 m
A student walks 20 m east, then 7 m west. Calculate their displacement.
20 − 7 = 13 m east
A runner travels 240 m in 30 s. Calculate their average speed.
240 ÷ 30 = 8 m/s
A cyclist has a displacement of 120 m east in 20 s. Calculate the average velocity.
120 ÷ 20 = 6 m/s east
A distance–time graph shows an object travelling from 0 m to 150 m in 30 s. Calculate its speed.
150 ÷ 30 = 5 m/s
A student walks 250 m to school, then walks 80 m back to get something, then walks another 80 m toward school. Calculate the total distance travelled.
250 + 80 + 80 = 410 m
A runner travels 100 m north, 40 m south and then 25 m north. Calculate the runner's displacement.
100 − 40 + 25 = 85 m north
A car travels 150 km in 2 h and then another 90 km in 1 h. Calculate its average speed for the whole trip.
Distance = 240 km; time = 3 h; speed = 80 km/h
A person walks 150 m east and then 50 m west. The total journey takes 40 s. Calculate their average velocity.
Displacement = 100 m east; velocity = 100 ÷ 40 = 2.5 m/s east
A car travels 200 m in the first 20 s, stops for 10 s, then travels another 300 m in 30 s. Calculate its average speed for the entire journey.
Distance = 500 m; time = 60 s; speed = 8.33 m/s
