Question

A man speaks 180 words per minute. The rate at which he speaks is words per second.

Answer 1

Given,
A man speaks 180 words per minute
Rate of speaking = 180 words per min
$=180÷60$ words per sec $\because 1\text{min}=60\text{sec}$
On simplifying,
$=\frac{3\times 6\times 10}{6\times 10}$
$=3$ words per sec
Hence, the rate of speaking is 3 words per sec.
