Answer: 1 hour 15min
Step-by-step explanation:
When Paul passes the gas station Mary si already 12.5 miles away
X=v t = 50mph 0.25h = 12.5 miles. (15min equals a quarter hour)
From that moment to the meeting point we’ll have only one t (time) and one x (final point) for both cars
For Mary we have
X= Xo + v t= 12.5 miles + 50mph t
For Paul we have
X=v t = 60mph t
As x si the same in both equations
60mph t = 12.5 miles + 50mph t
(60mph - 50mph) t = 12.5miles
10mph t = 12.5miles
t = 12.5miles/10mph
t = 1,25 h
