A car moved 654 m in 24.1 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

To begin, identify the formula given: speed = distance moved / time taken. The distance is 654 m and the time is 24.1 s, so the raw calculation is 654 / 24.1.
Next, perform the division: 654 ÷ 24.1 ≈ 27.125... m/s.
Now consider significant figures. The inputs have 3 significant figures each (654 has 3, 24.1 has 3), so the result should be reported with 3 significant figures.
Rounding 27.125... to 3 sig figs yields 27.1 m/s.
Therefore, the speed of the car, to the appropriate number of significant figures, is 27.1 m/s.
Note on units: speed is distance per time, so the units are meters per second (m/s).
