Caroline places five poles A, B, C, D, and E in order along a straight line.The distance between poles A and D is 1 yard. The distance between poles B and C is the same as the distance between poles A and B. Poles A and B are 1/5 yard apart. The distance between D and E is 7/10 10 yard. How far apart are poles B and E?
1/5 + 3/5 + 7/10 just add these
I got the 3/5 for C-D by subtracting
the 1/5 for A-B and 1/5 for B-C from the 1 for A-D.
Poles a and b are 1/5 yard apart . The distance between d and e is 7/10 yard how far apart are poles b and e ?
To find out how far apart poles B and E are, we need to determine the distance between poles A and E first.
Given the information provided:
- The distance between poles A and D is 1 yard.
- The distance between D and E is 7/10 yard.
To find the total distance between poles A and E, we can add the distance from A to D and the distance from D to E:
1 yard + 7/10 yard = 1 + 0.7 = 1.7 yards.
Now, we know the total distance between poles A and E is 1.7 yards.
Next, let's find the distance between poles A and B:
Poles A and B are 1/5 yard apart.
Therefore, the distance between poles A and B is 1/5 yard.
Now, we have the distance between poles A and E (1.7 yards) and the distance between poles A and B (1/5 yard).
To find the distance between poles B and E, we subtract the distance between poles A and B from the total distance between poles A and E:
1.7 yards - 1/5 yard = 1.7 - 0.2 = 1.5 yards.
Therefore, the distance between poles B and E is 1.5 yards.
To determine the distance between poles B and E, we can follow these steps:
Step 1: Calculate the distance between poles A and C.
Since the distance between poles A and B is 1/5 yard, and the distance between poles B and C is the same as between poles A and B, we can conclude that the distance between poles A and C is 1/5 + 1/5 = 2/5 yard.
Step 2: Calculate the distance between poles C and D.
Given that the distance between poles A and D is 1 yard, and we know the distance between poles A and C is 2/5 yard, we can subtract the length of poles C to get the distance between poles C and D: 1 - (2/5) = 3/5 yard.
Step 3: Calculate the distance between poles C and E.
The problem states that the distance between poles D and E is 7/10 yard. Since the distance between poles C and D is 3/5 yard, we can subtract the length of poles D to get the distance between poles C and E: (7/10) - (3/5) = 1/10 yard.
Step 4: Calculate the distance between poles B and E.
The question asks for the distance between poles B and E. Therefore, we need to add the distances between poles B and C and poles C and E together: (2/5) + (1/10) = 5/10 + 1/10 = 6/10 = 3/5 yard.
So, the distance between poles B and E is 3/5 yard.
