Problema Solution
two cities are 609 miles apart with a scenic highway connecting them. Sue lives in one city and john lives in the other. At the same time they both begin driving toward each other. Sue drives at a rate of 39 mph and john drives at a rate of 48 mph. If they both maintain their speeds throughout their entire drive, how long will it take for them to meet?
Answer provided by our tutors
Let
v1 = 39 mph the rate of Sue
v2 = 48 mp the rate of John
d = 609 mi the distance between them
t = the time of the travel, t>0
since speed = distance/time follows distance = speed*time:
v1t + v2t = d
39t + 48t = 609
........
........
t = 7 hr
It will take them 7 hours to meet.
