THE WORLD OF SCIENCE: Measurements of Speed
Speed is defined as:
Time ÷ Distance.
Distance ÷ Time.
Distance × Time.
Force ÷ Mass.
An object moves 15 m in 5 s. Its speed is:
3 m/s.
15 m/s.
5 m/s.
2 m/s.
A car moves 200 m east in 20 s, then 200 m west in 40 s. Total distance and displacement are:
400 m; 0 m.
200 m; 200 m.
200 m; 0 m.
400 m; 200 m.
Speed is calculated as:
Time ÷ Distance.
Mass ÷ Volume.
Distance ÷ Time.
Force ÷ Mass.
