Question

Maria has already written  of her 1,000 word essay. If she continues writing at the same pace of 6 words per minute, which expression shows the amount of time it will take her to write the rest of the essay?

Answer 1

167 minutes

Explanation:

Given:

The number of words per easy = 1,000

Speed = 6 words per minute

Time to write the full easy = ?

Solution:

Speed = words/minutes

Total time = total words/speed

By putting values in the formula:

Time = 1000/6

Time = 166.67 minutes

Hence the total time taken by maria to write 1000 words will be 166.67 minutes or 2 hours and 47 minutes.

Answer 2

The first thing we must do in this case is to define variables:
t = time to write the words
v = write speed.
w = number of words.
The correct expression is:
t = w / v
By substituting we have:
t = 1000/6
t = 166.6666667
Rounding:
t = 167 minutes
Answer:
The correct expression is:
t = w / v
The time is:
t = 167 minutes
