<h2>22 minutes 44 seconds</h2>

Step-by-step explanation:

1st horse time taken = 65 min/job; invert to get rate = 1/65 job/min

2nd horse time taken = 35 min/job ; invert to get rate = 1/35 job/min

Together Time taken = n min/job ; invert to get rate = 1/n job/min

------------------

Equation :-

Rate + Rate = together rate

1/65 + 1/35 = 1/n

-----------------------------

35n + 65n = 35*65

-----------------

100n = 2275

n = 22.75 minutes = 22 minutes 45 seconds
