Question 882621: two trains leave station. 304 miles apart at the same time and travel towards each other. one train travels at 105 miles per hour while the other travels at 85 miles per hour. how long will it take for the two trains to meet
Answer by algebrahouse.com(1659) About Me  (Show Source):
You can put this solution on YOUR website!
Distance = rate x time
d = rt

One train
distance = d
rate = 105
time = t {the two trains left at same times}
d = 105t {distance = rate x time}

Other train
distance = d
rate = 85
time = t {the two trains left at same times}
d = 85t {distance = rate x time}

105t + 85t = 304 {the two trains' combined distance equals 304}
190t = 304 {combined like terms}
t = 1.6 {divided each side by 190}

the two trains will meet in 1.6 hours
which is 1 hour and 36 minutes
