Question 1124070
<br>
Here is a completely different way to solve the problem than shown by the other tutor.<br>
The ratio of speeds going and returning is 140:110 = 14:11.<br>
Since the distances are the same, the ratio of times is 11:14.<br>
So the amount of time going from A to B is 11/25 of the total of 6 hours:
6*(11/25) = 66/25 hours.<br>
Try both methods and see what works best for you.<br>
Better yet, think about other ways to solve the problem and see if you find a way that is even easier for you.
