Let x be the total number of papers that need to be delivered.
Number of papers Candy can deliver in 1 minute =x/85
Number of papers Tim can deliver in 1 minute =x/65
Time taken for both Tim and Candy all the papers together =x/ (x/85 +x/65)
= x/ (150x/ 5525)
=221/ 6 minutes
=36 minutes 50 seconds
It takes Tim and Candy 36 Minutes and 50 Seconds to deliver all the papers when they work together.
I hope this helps \(^_^)/
