1. How do you calculate rate of anything….ex: miles per hour

2. What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?

3. What if you walked 6.00miles±0.05miles in 2.00hours±0.05hours?

4. Compare % uncertainties? Example A: “What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?” =3.0miles/hour ±33% Example B: “What if you walked 6.00miles±0.05miles in 2.00hours±0.05hours?” =3.00miles/hour ±3.3% Why does example B have less uncertainty than sample A?

5. What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?

6. What if you walked 30.0miles±0.5miles in 10.0hours±0.5hours?

7. Compare % uncertainties? Example A: “What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?” =3.0miles/hour ±33% Example C: “What if you walked 30.0miles±0.5miles in 10.0hours±0.5hours?=3.00miles/hour ±6.7% Why does example C have less uncertainty than sample A?
