Answer:
24 minutes
Step-by-step explanation:
Time taken by first gardener = 40 minutes
Work done by him in 1 minute = 1/40
Time taken by second gardener = 60 minutes
Work done by him in 1 minute = 1/60
Work done by both in 1 minute = 1/40 + 1/60 = 5/120 = 1/24
Hence, if both work simultaneously, it would take 24 minutes to mow the lawn.
