Answer:
she spent 20 minutes bathing the dog
Step-by-step explanation:
If Dina started at 8:15 and finished at 9:05 we have to calculate how many minutes were
from 8:15 to 9 there are 45 minutes, so at that 45 minutes we add the 5 minutes to 9:05 and we have
45+5 = 50 minutes
if it takes 30 minutes to clean your room, we have to subtract them after 50 minutes
50 - 30 = 20 minutes
she spent 20 minutes bathing the dog
