Question 898579: John and Mary, two longtime friends, are located in two separate towns that are two hundred miles apart connected by a straight highway. They decide to meet one another along the highway. John starts driving at 9:00 AM traveling at 60 mph(miles per hour). Mary starts driving at 9:00 AM at 40 mph. What time do they meet? How far is the meeting point from the midpoint of the two towns? Assume that their speeds do not change and that they do not stop along the trip. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! John travels x miles to meet Mary at 60 mph
Mary travels 200-x miles at 40 mph
t= d/r
x/60 = (200-x)/40
40x = 60(200-x)
40x = 12000-60x
100x= 12000
x= 120 miles
they are 20 miles away from mid point
they meet after 2 hours
