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 $d = 1000\space m$ and $v = 28\space m/s$. 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 options have labels, adjust the label accordingly. Since the user's image shows the purple option as 36 seconds, the answer is the option with 36 seconds, e.g., if the options are labeled as A:28 seconds, B:36 seconds, C:28,000 seconds, D:972 seconds, then the answer is B. 36 seconds)
