Question

PLEASE HELP ASAP!!!!

Answer 1

ill give the second one.

Carpenter's rate of work = 1/2 units per hour

Assistant's rate of work = 1/3 units per hour

Their combined rate of work = 1/2+1/3 units per hour

=5/6 units per hour

So, time required to do the job together

= 1/(5/6) hours

= 6/5 hours
