Question 1202648
<font color=black size=3>
Draw a number line to mark these three locations<ul><li>B = Bob's starting location</li><li>G = golf course location</li><li>J = Jim's starting location</li></ul>We have these segment pieces:<ul><li>GJ = x = distance from Jim to golf course</li><li>BG = x+15 = distance from Bob to golf course</li></ul>Those two pieces must add to the 95 mile gap between the two brothers. I'm assuming the golf course is between them.
GJ + BG = 95
x + (x+15) = 95
2x + 15 = 95
2x = 95-15
2x = 80
x = 80/2
x = 40


Jim travels x = 40 miles.
Bob travels x+15 = 40+15 = 55 miles.


Jim travels 40 miles in 1 hour, which is the time gap from 8:00 to 9:00.
Jim drives at 40 mph (average).
Formula is: rate = distance/time


40+10 = 50 mph is Bob's average speed.


Let's determine how long Bob would take to travel 55 miles at 50 mph.
distance = rate*time
time = distance/rate
time = 55/50
time = 1.10 hours


The 0.10 hour portion converts to 0.10*60 = 6 minutes
1.10 hours = 1 hour + 6 minutes


Bob is on the road for 6 additional minutes compared to his brother. 
He'll need to rewind the clock 6 minutes into the past to be able to arrive at 9:00


8:00 - 6 minutes = 7:54


In other words,
7:54 + (1 hr & 6 min) = 9:00

I'm not sure whether to put AM or PM. The instructions are vague about that. It could be possible that your teacher is using 24 hour time format.
