To find the time when Dora and her brother Kyle started doing yard work, we need to subtract the time they spent doing yard work from the time they stopped for lunch.

Given:
- Time spent doing yard work: 1 hour and 35 minutes
- Time stopped for lunch: 1:20 p

Let's convert the time spent doing yard work into minutes:
1 hour = 60 minutes
1 hour and 35 minutes = 60 + 35 = 95 minutes

Now, we can subtract the time spent doing yard work from the time they stopped for lunch to find the start time:
1:20 p - 95 minutes

Let's calculate the start time.
Calculate the value by following steps:
- step0: Calculate:
  $$1\div 20-95$$
- step1: Divide:
  $$0.05-95$$
- step2: Subtract the numbers:
  $$-94.95$$
The start time when Dora and her brother Kyle started doing yard work is approximately 1:20 p - 95 minutes, which is equivalent to 1:20 p - 1 hour and 35 minutes.

Therefore, they started doing yard work at approximately 11:45 a.m.
They started doing yard work at approximately 11:45 a.m.
