Question

a car moves a distance of 1000 m with an average speed of 28 m/s. calculate the time. 28 seconds 36 seconds 28,000 seconds 972 seconds

Explanation:

Step1: Recall the formula for time

The formula relating speed ($v$), distance ($d$), and time ($t$) is $t = \frac{d}{v}$.

Step2: Substitute the given values

We know that $d = 1000\ m$ and $v = 28\ m/s$. Substituting these values into the formula, we get $t=\frac{1000}{28}$.

Step3: Calculate the value

$\frac{1000}{28}\approx35.71$, which is approximately 36 seconds.

Answer:

B. 36 seconds (assuming the purple option is labeled B, if the original labels were A:28 seconds, B:36 seconds, C:28,000 seconds, D:972 seconds)
