Two trains, Train A and Train B, weigh a total of 366 tons. Train A is heavier than Train B. The difference of their weights is
190. What is the weight of Train A?
1 answer:
Answer:
278 tons
Step-by-step explanation:
Given data
Train A and Train B, weigh a total of 366 tons
A+B= 366----------1
We are also given that
A-B= 190-----------2
from 1
A= 366-B
put this in equation 2, we have
366-B-B= 190
366-2B= 190
366-190= 2B
176=2B
divide both sides by 2
B= 176/2
B=88 tons
Put B= 88 in equation 1 to find A
A+88= 366
A= 366-88
A=278 tons
Hence Train A is 278 tons
