Answer:
Time taken by A to complete a work= 15 min
Therefore, Work done by A =1/15 part of work
Time taken by B to complete the work = 45 min
Therefore, Work done by B = 1/45 part of work
Therefore, Total work done by both A and B = 1/15+1/45=(3+1) /45=4/45 part of work
Therefore, Time taken by them together to do the same work=45/4=11•25 hr
