On another day, the person ran the same route. What is a typical speed for a person running?
Answer options:
A.
0.3 m/s
B.
3.0 m/s
C.
30 m/s
How to approach this question
Consider the typical speeds for human activities. You should have an idea of the order of magnitude for walking, running, and cycling. Compare the given options to these typical values.
Full Answer
B.3.0 m/s✓ Correct
3.0 m/s
It is useful to remember some typical speeds:
- Walking: ~1.5 m/s
- Running: ~3 m/s
- Cycling: ~6 m/s
Let's evaluate the options:
- 0.3 m/s is very slow.
- 3.0 m/s is a reasonable speed for a person running or jogging.
- 30 m/s is about 67 miles per hour, which is the speed of a car on a motorway. This is far too fast for a human.
Common mistakes
✗ Not having a sense of scale for speeds in m/s.\n✗ Choosing 30 m/s, which is superhumanly fast.
