A car moved 665 m in 18 s. Using the formula [math: speed=distance movedtime taken]speed = \frac{distance\ moved}{time\ taken} calculate the speed of the car to the appropriate number of significant figures.

Question

BlackTom AI · Accepted Answer

The problem gives distance moved = 665 m and time taken = 18 s, and asks for speed using speed = distance / time.
First, compute the raw quotient: 665 m ÷ 18 s ≈ 36.944... m/s.
Next, consider significant figures: 665 m has 3 significant figures, and 18 s has 2 significant figures. The result should be reported with the same number of significant figures as the measurement with the fewest significant figures, which is 2 sig figs from the time value.
Rounding 36.944... m/s to 2 sig figs gives 37 m/s.
Therefore, the calculated speed is 37 m/s when expressed with the appropriate significant figures. If you were to keep more digits without the sig-fig constraint, you would have 36.94 m/s (or 36.944... depending on rounding policy), but the correct presentation per the given data is 37 m/s.
Note: There are no answer choices provided to compare against in this question.
