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.
