Mrs. Michael left her home at 06 30 to a nearby park for some morning exercise. She left her house and took a 22 min walk to the park. She stayed at the park for some time and took the same route back. She reached home at 08 06. Given that she took the same time to walk home from the park, how long did Mrs. Michael exercise at the park last?
From 06 30 to 07 00 = 30 min
From 07 00 to 08 06 = 1 h 6 min

Total time taken
= 30 min + 1 h 6 min 
= 1 h 36 min 

1 h = 60 min

Time that Mrs. Michael spent to walk to the park and back home
= 2 x 22 
= 44 min

Time that Mrs. Michael spent to exercise in the park
= 1 h 36 min - 44 min
= 96 min - 44 min
= 52 min

Answer(s): 52 min
