krek1111 [17]

We are given

It takes a word processor 22 minutes to word process and spell check 4 pages

so, firstly we can find rate

total time =22 min

number pf pages =4

processing rate = ( number of pages)/( total time)

So, processing rate is

=\frac{4}{22}

R=\frac{2}{11} page /min

now, we are given total number of pages =26

Time = (total number of pages)/( processing rate)

so, time is

=\frac{26}{\frac{2}{11}}

now, we can simplify it

=\frac{26}{\frac{2}{11}}

=143

So, the time taken to word process and spell check 26 pages is 143 min........Answer
