Answer: Without GUI's being developed, we most likely would still be using terminal systems. Terminals require command/text input rather than mouse or other input. The invention of GUI's enabled people to use simpler input methods, rather then clunky text input systems. To sum, GUI's simplified the computer experience as we know today.

It would take 2 consultants 30 hours to create a slide deck of 120 slides.
Explanation:
Rate of slide making by one consultant- 2 slides per hour
Target- 120 slides
2 consultants are employed in the job-
Since 2 consultants are employed in the job, total rate of making slides per hour would be 4 slides/hour (2*2 slides/hour)
Time required to complete 120 slides= total slides/rate of doing slides per hour
Substituting the values, we get
Time required= 120/4= 30 hours
Hence, it would take 30 hours for 2 consultants to create a slide deck of 120 slides.
