How many words can thE student read in 8 mins
How long would I take for the student to read 2,850 words
Plz help

Answer 1

The student can read 150 words in one minute, therefore:

let x = the number of minutes the student reads.
let f(x) = the total number of words read

The student can read 150 words per minute, so multiplying 150 by the number of minutes would give the total number of words read.

The expression 150x represents this. It is also equal to what we have defined as f(x). Therefore:

f(x) = 150x

Replacing 2,850 (the number of words the student has read) with f(x) gives:

2,850 = 150x

Solving for x gives:

2,850/150 = x

19 = x

Since x = the number of minutes the student has read, x = 19 means that the student has read 2,850 words in 19 minutes.
