During a field experiment about speed, a scientist created the chart above. The chart shows distance and time measurements for a racing car on the straight section of a race track. What is the racing car's speed?

Question 13 options:

192 m/s


384 m/s


96 m/s


0 m/s

time:0,1,2,3,4,
distances:0,96,192,288,384

Answer 1

To calculate the speed of the racing car, we can use the formula for speed:

\[
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
\]

From the provided data:

- At \( t = 0 \) seconds, the distance is 0 meters.
- At \( t = 1 \) second, the distance is 96 meters.
- At \( t = 2 \) seconds, the distance is 192 meters.
- At \( t = 3 \) seconds, the distance is 288 meters.
- At \( t = 4 \) seconds, the distance is 384 meters.

We'll calculate the speed using the total distance covered over the total time taken. The car covers a distance of 384 meters in 4 seconds.

Now applying the formula:

\[
\text{Speed} = \frac{384 \text{ meters}}{4 \text{ seconds}} = 96 \text{ m/s}
\]

Thus, the racing car's speed is **96 m/s**.

The correct option is:

**96 m/s**
