A hawker takes 1.25 hours to deliver newspapers on his route. Another hawker takes 15 minutes longer to deliver these papers on the same route. How long would it take to deliver the papers if both of them worked together?

First hawker takes 1.25 hours or 75 minutes and second hawker takes 75 + 15 = 90 minutes.
Together they can finish (1/75 + 1/90) = 11/450 part of the delivery in 1 minute.
So, together they will finish the whole delivery in 1/(11/450) = 450/11 = 40.91 minutes.
