Seven water stations were set up at regular intervals along the 42-kil...

Steps 1 & 2: Understand Question and Draw Inferences

Given: The 7 water stations are set up at REGULAR intervals

Let’s mark the Starting Point of the marathon as Zero
The 7 water stations are then situated as under:

James:
- Total distance run = 42 km
- Uniform speed
- No turning back

To Find: Time taken by James to run 42 km

To find Time, we need to find his running speed

Step 3: Analyze Statement 1 independently

(1) 40 minutes after the start of the marathon, James was 4 kilometers away from the second water station

2^nd water station = 12 km from Starting Point
For Time = 40 min, Distance run =
- (12 + 4 =) 16 km OR
- (12 – 4 = ) 8 km
So running speed =
- 16/40 km per min OR
- 8/40 km per min

Since we don’t get a unique value of running speed, Statement 1 is not sufficient to get a unique answer

Step 4: Analyze Statement 2 independently

(2) 20 minutes before reaching the finish point, James was 20 kilometers away from the third water station

3^rd water station = 18 km from Starting Point
Position 20 minutes before Reaching Finish Point =
- (18 - 20 =) -2 km OR
- (18 + 20 = ) 38 km

James never turned back (given)
- So, he could not be at position -2 km

So, James’ position 20 minutes before Reaching Finish Point = 38 km
- Distance run in last 20 min = (42 – 38) km = 4 km
- Speed in last 20 min = 4/20 km per min
(Since his speed is uniform) James’ Speed throughout the run = His Speed in last 20 min = 4/20 km per min

Since we now know his speed, we can find the time he took to run the entire marathon.

Sufficient

(Alternate analysis once it is determined that Distance run in last 20 min = 4 km:

Time taken to run 4 km = 20 min

Time taken to run 42 km = 20/4 ∗ 42 min

This method too is valid only under the condition of uniform speed)

Step 5: Analyze Both Statements Together (if needed)

Since we arrived at a unique answer in Step 4, this step is not required

Answer: Option B
