<h2>
<u>22 minutes 44 seconds</u></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 = <em>n</em> min/job ; invert to get rate = 1/<em>n</em> job/min
------------------
Equation :-
Rate + Rate = together rate
1/65 + 1/35 = 1/n
-----------------------------
35<em>n</em> + 65<em>n</em> = 35*65
-----------------
100<em>n</em> = 2275
<em>n</em> = 22.75 minutes = <u>22 </u><u>minutes</u><u> 45 </u><u>seconds</u>
