Question

menu has already typed 250 words he then starts a timer and finds that he types 150 words in 3 minutes if menu types at a constant rate write an linear equation to represent the number of words w nebi types m minutes after starting the timer

Answer 1

w = (50 wds/min)*m, where m is in minutes

Explanation:

Let's start by calculating the tying rate, in words per minute.

We know:

150 words (wds)

3 minutes (min)

So we can write: (150 words)/(3 minutes) = 50 words/minute or 50 wds/min

An equation that would allow us to determine the number of words, w, after the timer starts counting minutes, m, we can write:

w = (50 wds/min)*m, where m is in minutes

====

Although not requested, the equation for total number of words since the start of the problem, we could write:

w = (50 wds/min)*m + 250wds
