The speed of a car is found using measurements of the distance travelled and the time taken. The distance is recorded as $200\ \text{m}$, with an uncertainty of $\pm 2\ \text{m}$. The time is recorded as $10.0\ \text{s}$, with an uncertainty of $\pm 0.2\ \text{s}$. What is the percentage uncertainty in the calculated speed?
- A$\pm 0.5\%$
- B$\pm 1\%$
- C$\pm 2\%$
- D$\pm 3\%$
