Ileave my family's vacation cabin at 8 a. m. and start driving home at a nice, safe 45 mph. two hours later, my husband, who always drives as fast as the law will allow, leaves the cabin and starts driving home 65 mph. when can i expect him to pass me?

2:30 pm

Step-by-step explanation:

In two hours (from 10am), she is 45 * 2 = 90 miles from vacation cabin.

From then on her average is still 45 mph and her husband's is 65 mph. So, husband catches her 20 miles (65-45=20) in every hour.

The husband has to catch up 90 miles. How long would it take if he is catching up at 20 miles an hour?

90/20 = 4.5 hours

So husband starts at 10am and 4.5 hours form that time is 2.30pm

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
