Answer:
Step-by-step explanation:
480 divided by 6 is 80, so she was initially traveling at 80 mph.
She then increased her speed by 20 mph, therefore making it 100 mph. (Someone arrest her already.)
560 divided by 100 is 5.6 hours.
0.1 of an hour is 6 minutes.
0.6 of an hour is therefore 36 minutes.
Your answer is 5 hours and 36 minutes.
