Answer by Olly B
A=speed of train A
B=speed of train B

1) A=B-10

2) 220A=270B
22A=27B
A=27/22B

2 in 1

27/22B=B-10
10=B-27/22B
10=B(1-27/22)
B=10/(1-27/22)
B=-9.773

A=-9.773 -10
A=.277
A=

Answer by kjatch
v=s/t
t=s/v

vA=vB-10
sA=220
sB=270
tA=tB

220 / (vB-10) = 270 / vB

220 vB = 270(vB-10)

vB=54
vA=44

Answer by indiano
1. Sa = Sb – 10
2. 220/Sa = 270/Sb

now solve:

220Sb = 270Sa
220Sb = 270 * (Sb – 10)
220Sb = 270Sb – 2700
50Sb = 2700
Sb = 2700/50 = 54 miles per hour.

Sa = 54-10 = 44 miles per hour

This is a mathematics “word” problem, and it belongs in the “HOMEWORK HELP” section. Just because it contains the word “train” does not make it a question for the “Rail” sub-section.

wow
that is awfully complicated
luckily I am the engineer on the slow train and dont have to do complicated math
