Question 930983: Don left Vancouver and drove towards hope Hope at a speed of 120 km/h. Brad left Hope at the same time and drove towards Vancouver at a speed of 90 km/h. If Hope is 122 km from Vancouver, how far had they each driven when they passed each other on the highway?
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! x = distance driven by Don when they meet
y = distance driven by Brad when they meet
t = time driven by each when they meet
---
s = d/t
t = d/s
d = st
---
their relative speed:
120 + 90 = 210 kph
---
t = 122/210
t = 0.580952380952 hours
---
x = 120*0.580952380952
x = 69.71
y = 90*0.580952380952
y = 52.29
---
answer:
x = distance driven by Don when they meet = 69.71 km
y = distance driven by Brad when they meet = 52.29 km
