I need the answer to this I've tried it about 3 times and still cant get it right.

Question

Jennifer left her house at 6:45 am. It took her 8 minutes 45 seconds to walk to the bus stop. She waited 3 3/4 minutes for the bus and then rode the bus 7 1/2 minutes to her school. At what time did she arrive at school?

Answer 1

Easier to convert minutes and seconds to decimal.

8:45 = 8.75

3 3/4 = 3.75

7 1/2 = 7.5

------

20 minutes

6:45 + 0:20 = 6:65 = 7:05 am
