Question

Marcy played the piano for 45 minutes. She stopped playing at 4:15 p.m. At what time did she start playing the piano?

Answer 1

Answer:

At 3:30 p.m. she started playing the piano

Step-by-step explanation:

We are given the following information:

Marcy played the piano for 45 minutes.

She stopped playing at 4:15 p.m.

This means that at 3:30 p.m. she started playing the piano.

( since 15 minutes before 4:15 om is 4:00 pm now 30 minutes more before 4:00 pm is 3:30 pm which adds up to:

15+30=45 min.)

Answer 2

Well, first off 1 hr =60 minutes. 60 min - 45 min = 15 minutes extra. what is one hour before 4:15? 3:15! Add the subtracted 15 minutes to get 3:30... Hope this helps
