Question

1. of the following, which equation does not correctly represent a relationship between distance, time and speed? a. distance equals speed multiplied by time. b. speed equals time multiplied by distance. c. time equals distance divided by speed. d. speed equals distance divided by time. clear selection

Explanation:

Step1: Recall the basic formulas

The well - known formulas for distance ($d$), speed ($s$), and time ($t$) are $d = s\times t$, $s=\frac{d}{t}$, and $t=\frac{d}{s}$.

Step2: Analyze each option

• Option a: $d = s\times t$ is correct.
• Option b: The correct formula for speed is $s=\frac{d}{t}$, not $s = t\times d$. So this option is incorrect.
• Option c: $t=\frac{d}{s}$ is correct.
• Option d: $s=\frac{d}{t}$ is correct.

Answer:

B. Speed equals time multiplied by distance.
