Gaby and her cousin, Fiona, live 45 km apart. Every day, they drive by one another to get to work. Gaby leaves home at 7:00 a.m. and drives at the road speed of 60 km/h. Fiona, however, always leaves home 20 min later and therefore speeds by 10 km/h. Approximately what time will Gaby meet Fiona on the road?
A brand-new engineering hire is late for her first product development team meeting. She gets out of her car and starts running 8 mph. It is exactly 7:58 a.m., and the meeting starts at exactly 8:00 a.m. Her meeting is
510 yd away. Will she make it on time to the meeting? If so, with how much time to spare? If not, how late will she be?
(Express your answer using two significant figures. Enter a negative value if the person will be late and a positive value if she will come earlier.)
