Question 905240: Two trains are 345 miles apart, and their speeds differ by 23 mph. Find the speed of each train if they are traveling toward each other and will meet in 3 hours Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 345=3*(x+y)
x+y=115
x-y=23
2x=138
x=69
y=46
check
345=69*t+46*t
345=115*t
t=3 hours
The total time for car from b to meet the car from a is 3 hours
d=R*t
d=46*3
d=138+0
d=138 miles from b at 46 mph
d=r*t
d=69*3
d=207 miles from a at 69 mph
