Answer:
1.2 hours
Step-by-step explanation:
John can do a job in 2 hours
Ben can do the same job in 6 hours
Let y represent the time it will take both men to do the job together
y/2 + y/6=1
5y/6= 1
Cross multiply
5y = 6
y= 6/5
y= 1.2
Hence it will take both of them 1.2 hours to finish the work together
