Mrs. Japheth left her home at 07 14 to a nearby park for some morning exercise. She left her house and took a 29 min walk to the park. She stayed at the park for some time and took the same route back. She reached home at 09 01. Given that she took the same time to walk home from the park, how long did Mrs. Japheth exercise at the park last?
From 07 14 to 08 00 = 46 min
From 08 00 to 09 01 = 1 h 1 min

Total time taken
= 46 min + 1 h 1 min 
= 1 h 47 min 

1 h = 60 min

Time that Mrs. Japheth spent to walk to the park and back home
= 2 x 29 
= 58 min

Time that Mrs. Japheth spent to exercise in the park
= 1 h 47 min - 58 min
= 107 min - 58 min
= 49 min

Answer(s): 49 min
