Mrs. Brown can jog 1 mile in 9 min. She can walk 1 mi in 15 min. She always stretches for 5 min before exercising. One day, she jogged 2 mi and walked 3 mi. If she finished at 9:15 a.m., what time did she start exercising?

Answer 1

First, let's calculate the total time it took for Mrs. Brown to jog and walk:

Jogging 2 mi at 9 min/mi = 2 * 9 = 18 minutes
Walking 3 mi at 15 min/mi = 3 * 15 = 45 minutes

Total time = 18 minutes + 45 minutes = 63 minutes

Adding 5 minutes for stretching before exercising, the total time she spent exercising is 63 minutes + 5 minutes = 68 minutes.

If she finished at 9:15 a.m., we can subtract 68 minutes to find out what time she started exercising:

9:15 - 1 hour = 8:15 a.m.
- 15 minutes = 8:00 a.m.

Mrs. Brown started exercising at 8:00 a.m.

Answer 2

Is this accurate? Bruh. 9:15-68 min?

If she finished at 9:15 a.m., we can subtract 68 minutes to find out what time she started exercising:

9:15 - 1 hour = 8:15 a.m.
- 15 minutes = 8:00 a.m.

Answer 3

Apologies for the confusion in the previous response. Let's correct the calculation:

If Mrs. Brown finished at 9:15 a.m. and she spent a total of 68 minutes exercising (including stretching), we need to subtract 68 minutes from 9:15 a.m. to find out what time she started exercising.

9:15 a.m. - 68 minutes = 8:07 a.m.

Therefore, Mrs. Brown started exercising at 8:07 a.m.
