Answer:
The answer is letter A, Ed, Derek, Mike, Tom
Explanation:
The question is asking for the order from the 1st to the 4th (first to last). All you have to do is to <em>follow the instruction or draw an illustration (if you can). </em>
If Derek is 10 yards ahead of Mike, this means that Derek's position is ahead of Mike.
If Mike is 5 yards ahead of Tom, then this means that Mike's position is ahead of Tom.
If Ed is 20 yards ahead of Derek, then this means that Ed's position is ahead of Derek.
If Derek is ahead of Mike, Mike being ahead of Tom and Ed being ahead of Derek, then you'll be able to tell the positions now.
This means that the 1st runner is Ed, while the second runner is Derek. The third runner is Mike, while the fourth runner is Tom.
Thus, this explains the answer.
