Question 823743: two high speed trains are 270 miles apart and traveling toward each other. they meet in 2 hours. if one trains speed is 10 miles per hour faster than the other, find the speed of each train
the speed of the slower train is? mph. (Round to two decimal places as needed.)
the speed of the faster train is? mph. (Round to two decimal places as needed.) Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! ---
s = d / t
s = 270 / 2
s = 135 mph
---
x = speed of trainA
y = speed of trainB
s = x + y
y = x + 10
---
s = x + x + 10
s = 2x + 10
---
2x + 10 = 135
2x = 125
---
x = 62.5
y = 72.5
---
answer:
speed of trainA = 62.5 mph
speed of trainB = 72.5 mph
