Answer 1

Answer:

16 hours

Step-by-step explanation:

10+6 is 16.

Answer 2

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.
