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

1 answer

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
