The speed ratio of the two trains is 4:3, that is, for every 4 hours that one train is delayed, the other is delayed 3.
<h3>How to find the speed ratio of the trains?</h3>
To find the speed ratio of the trains we must do the following operation:
- V1 =
- V1 =
- T =
- V2 =
- V1 : V2 = :
Note: This question is incomplete because there is some information missing. Here is the complete information in:
A train started from Howrah for Allahabad another train started from Allahabad for Howrah at the same time. The two trains reached their destinations in 9hours and 16 hours respectively after they meet each other. Find the ratio of speed of the two trains.

Answer:
A
Step-by-step explanation:
2/8 because there are 8 in total but only 2 are colored.
Answer:
A
Step-by-step explanation:
Group the 4 terms into groups of 2 without changing their order. That looks like this:
Now within each group pull out what's common:
Now we have (x + 3) common between the 2 terms, so let's pull that out. With grouping, you know that it "works" if what's in the parenthesis are both exactly the same term. Ours are both (x + 3). What's "left over" are the things we originally pulled out, so group those together and you're done!
A = √(18+b)(18-b), -√(18+b)(18-b)
b= √(18+a)(18-a), -√(18+a)(18-a)
take the root of both sides and solve I hope this helps
Answer:
So
Step-by-step explanation:
So the first thing you do is take 2x to the other side. so it becomes a-b-2x=-3y. then take -3 out of y so it becomes y=a-b-2x/-3..Tadadaaa
