• D. 45 minutes

Answer 1

The correct option is B 40 minutes

Answer: Option B

Explanation:
When it was 04:00, Ryan's watch showed 03:50
So, his watch is 10 minutes slower.

Time at which Ryan has to reach doctor = 08:50
Time at which Ryan reaches the doctor according to his clock = 09:20
As, Ryan watch is 10 minutes slow, original time at which Ryan reaches the doctor = 09:20 + 10 minutes
= 09:30

Minutes by which Ryan is late to the doctor = 09:30 - 08:50
= 30 minutes + 10 minutes
= 40 minutes
