Answer:
16 hours
Step-by-step explanation:
10+6 is 16.
Answer:
Sam takes 6 hours to complete the work that means he Completes the 1/6 amount of work in an hour,
also, Sam's friend takes 10 hours to complete the same work that means he completes the 1/10 amount of work in an hour,
now when they both will work together
the amount of work done in an hour will be
1/6+1/10=8/30
now simply invert it to get the time taking by both to complete the work
i.e., 30/8 or 3.75 hours.
