Mrs. Vincent left her home at 07 19 to a nearby park for some morning exercise. She left her house and took a 23 min walk to the park. She stayed at the park for some time and took the same route back. She reached home at 09 04. Given that she took the same time to walk home from the park, how long did Mrs. Vincent exercise at the park last?
From 07 19 to 08 00 = 41 min
From 08 00 to 09 04 = 1 h 4 min

Total time taken
= 41 min + 1 h 4 min 
= 1 h 45 min 

1 h = 60 min

Time that Mrs. Vincent spent to walk to the park and back home
= 2 x 23 
= 46 min

Time that Mrs. Vincent spent to exercise in the park
= 1 h 45 min - 46 min
= 105 min - 46 min
= 59 min

Answer(s): 59 min
