Terry, Barry, Larry, Jerry, and Perry are lined up in these positions midway through a track meet: Terry is 20 meters behind Barry. Barry is 50 meters ahead of Larry. Larry is 10 meters behind Perry. Jerry is 30 meters ahead of Terry. Perry is 50 meters behind Jerry. At this point in the race, who is winning? Who is second? Third?
Jerry and perry
Jerry is winning
Berry is second
Terry is third

Ha and together they still ain't gt one brain sell
Well, let's see if I can untangle this hilarious mess! It sounds like these guys are having quite the run. So, based on the given information, I can deduce the positions:
- Terry is 20 meters behind Barry.
- Barry is 50 meters ahead of Larry.
- Larry is 10 meters behind Perry.
- Jerry is 30 meters ahead of Terry.
- Perry is 50 meters behind Jerry.
Now, who's in the lead? Let me break it down:
- Terry is behind Barry by 20 meters, so Terry's current position is 30 meters behind Larry.
- Larry is 10 meters behind Perry, which means Terry is 40 meters behind Perry at this point.
- Jerry is 30 meters ahead of Terry, so Jerry is leading the race.
- Barry is ahead of Terry, but Jerry is even farther ahead, so Barry is in second place.
- Perry is behind Jerry, Terry, and Barry, putting him in fourth place.
- That leaves Larry in fifth place, trailing behind Terry and Perry.
So, the standings are as follows:
- Jerry is winning the race.
- Barry is in second place.
- Terry is in third place.
- Perry is in fourth place.
- Larry is in last place.
That's one delightful race full of peculiar positions!
To determine who is winning, second, and third in the race, we need to calculate the distances of each runner from the starting point. Let's break down the given information and calculate the distances of each runner:
1. Terry is 20 meters behind Barry.
Distance from the starting point: Barry's distance + 20 meters
2. Barry is 50 meters ahead of Larry.
Distance from the starting point: Barry's distance
3. Larry is 10 meters behind Perry.
Distance from the starting point: Perry's distance + 10 meters
4. Jerry is 30 meters ahead of Terry.
Distance from the starting point: Terry's distance - 30 meters
5. Perry is 50 meters behind Jerry.
Distance from the starting point: Jerry's distance + 50 meters
Now, let's assign placeholder variables for each runner's distances:
- Let T represent Terry's distance.
- Let B represent Barry's distance.
- Let L represent Larry's distance.
- Let J represent Jerry's distance.
- Let P represent Perry's distance.
With this information, we can create a system of equations:
1. T = B - 20
2. B = L + 50
3. L = P - 10
4. J = T + 30
5. P = J - 50
To solve this system, we can start from any given equation and substitute variables until we reach a solution. Let's start with equation 2:
B = L + 50 [equation 2]
Since B is equal to L + 50, we can substitute L + 50 for B in equation 1:
T = (L + 50) - 20
T = L + 30 [equation 1a]
Now, equation 3 becomes:
L = P - 10 [equation 3]
Substituting L for P - 10 in equation 4:
J = (L + 30) + 30
J = L + 60 [equation 4a]
And equation 5 is:
P = J - 50 [equation 5]
Now, we have equations 1a, 2, 3, 4a, and 5 to work with. Let's substitute equations 1a and 3 into equation 2:
L + 30 = (P - 10) + 50
L + 30 = P + 40
L - P = 10 [equation 6]
Equations 4a and 5 can also be simplified:
J - P = 50 [equation 7]
Now, we have two equations, 6 and 7, to solve simultaneously:
L - P = 10
J - P = 50
By subtracting equation 6 from equation 7, we can eliminate P:
(J - P) - (L - P) = 50 - 10
J - L = 40
This equation tells us that Jerry is 40 meters ahead of Larry.
Now, we can find the distances of Terry and Perry using equations 1a and 3:
T = L + 30
T = (40) + 30
T = 70 meters
P = L + 10
P = (40) + 10
P = 50 meters
So, the final distances for each runner are as follows:
- Terry: 70 meters
- Barry: 40 meters
- Larry: 40 meters
- Jerry: 40 meters
- Perry: 50 meters
Since Terry is in the lead with 70 meters, followed by a three-way tie between Barry, Larry, and Jerry at 40 meters, and Perry at 50 meters, Terry is winning the race. Barry, Larry, and Jerry are all tied for second place. Perry is in third place.
