Average speed is calculated using [...]\text{[...]}[...].
A
Typical speeds are about 1.5 m/s\boxed{1.5\ \text{m/s}}1.5 m/s for walking and 330 m/s330\ \text{m/s}330 m/s for sound in air.
B
The gradient of a velocity-time graph gives acceleration.
C
Average speed is calculated using v=st\boxed{v=\dfrac{s}{t}}v=ts.
D
Near Earth's surface, free-fall acceleration is approximately 10 m/s210\ \text{m/s}^210 m/s2 downwards.
