Answer:
He drove for 1 hour and 30 minutes, and started driving at 12:45pm
Step-by-step explanation:
Firstly, you deduct 60 and 90. That means that he has been driving one hour, then the remainder is 30, which means that at the speed of 60mph he traveled that much in half an hour. Then you add the 15 more minutes to the time of the meeting (don't let this confuse you, don't try to add the 15 more minutes to the time that he traveled, but to the end time). That means that he drove for a total of 1 hour and 30 minutes. Now you just move the clock back from 2:15 pm for 1 hour and 30 minutes. That means that he started driving at 12:45 pm
(this confused me so much and I don't know why, but I hope I helped)

Answer:
y = 3
Step-by-step explanation:
<em>*As seen in the photo, the fact that EF = GF and the bisector being there makes EH = HG.</em>
<u>5y + 10 = 28 - y</u>
<em>*Add y to both sides.</em>
6y + 10 = 28
<em>*Subtract 10 from both sides.</em>
6y = 18
<em>*Divide both sides by 6.</em>
y = 3
